Ten years of digital documentation in Asia Minor
The Built Heritage always tells the story of the human actions that conceived, constructed,
altered, transformed, used, or even demolished it, whether in proper or improper ways.
In the brief moment when we encounter a monument, a ruin, or an archaeological site, we
perceive the resonance of those intentions and events that have succeeded one another
over time in that very place. This is a phenomenon of superimpositions and integrations
that has taken shape through an extended temporal process, defined by human choices and
natural occurrences, leading to the appearance that these architectures present today.
This appearance is itself destined to evolve further. The ability to read and interpret
what emerges before our eyes is a complex operation, requiring rigorous preparation,
specific skills, and a refined capacity for intuition. Over the past ten years, a sustained
effort to promote educational activities dedicated to architecture in its most intricate
historical forms, carried out with students (mainly in architectural training), colleagues,
and collaborators, has, through both personal circumstances and fortuitous events, led
to the collection of a series of experiences in Asia Minor, in contemporary Turkey. These
experiences have been grounded in seminars conducted in places of exceptional value
and fascination, consistently combining documentation and knowledge acquisition with
surveying practices, contemporary technologies, and the active transmission to participants
of new abilities in representation, thinking, abstraction, comprehension, invention, and
design. All of this has been achieved through interdisciplinary and collaborative approaches,
often within limited timeframes, but it is hoped that with meaningful outcomes, capable
of embedding what was learned into the future experiences of architects and specialists
devoted to the extensive built and artistic heritage encountered in diverse contexts. In
this issue of *Archeomatica*, we are pleased to present a collection of excerpts from
the workshops held between 2014 and 2025 in contexts of great architectural and urban
complexity. All these initiatives share the intent to balance technology, education, and
the capacity to produce outputs that serve an intelligent use of knowledge and a deeper
understanding of the value of cultural heritage. A crucial transition, therefore, is to view
the creation of digital heritage not as a mere mechanical act, but as an opportunity
to stimulate, cultivate, and consolidate passion and interest for the specific values
embodied in each place, building, and fragment, fostering a productive evolution that
bridges experience and culture. In the pages that follow, the proposed itinerary begins
on the island of Cyprus, then moves to, and repeatedly returns to, Istanbul, a key hub of
exchanges and intersections between historical and architectural periods. It proceeds to
more recent explorations of cities in the Hellenistic area and concludes with a reflection
on itinerant artistic elements, which are often “restless” components in the Cultural
Heritage scenario and that demand particular and attentive consideration.
Enjoy your reading!

Built Heritage in Cyprus
FIRST WORKSHOP IN CYPRUS:
ACHEROPOIETOS MONASTERY
The first one was held in the
Monastery called “Παναγία
Aχειροποίητος” which gets
the name from the presence
of a sacred icon said to be
«made without hands» which
was one of the main relics in
the church (Enlart, 1899). In
this artwork there was the
representation of the Virgin
Mary, a work which was consiby
Alessandro Camiz, Carmine Canaletti and Zeynep Ceylanlı

The two workshops held in Cyprus in collaboration with
the Girne American University and the Ozyegin University,
Istanbul, were aimed to the documentation and rethinking
of new uses for the historical Built Heritage of the
Acheiropoietos Monastery, in 2014, and of the Kyrenia
Castle, in 2018. They were the first activities of this kind
and showed how teaching, documentation and research
can be applied all together in complex cultural heritage
environments.

dered as created in a “miraculous”
way, and thus protected
from any possible iconoclasm.
The date of its foundation is not
known, thus, the katholikon appears
to have been built during
the XIth or early XIIth century
(Canaletti & Camiz, 2016). The
first written references to the
monastery are no older than
the XVth century.The analysis
of the building revealed the
presence of several consecutive
construction phases: for first
relevant architecture is a central
plan church covered with
a dome, probably built in the
late-Byzantine period on the
ruins of a paleo-Christian basilica,
characterized by three-naves,
then extended with three
narthexes, this transformation
changed the general aspect of
the plan layout into the one of
a longitudinal basilica. The construction
of an enclosure wall
around the church marked the
limits of the monastery, this intervention
was done in a series
of phases, following a variety of
expansions, demolitions and restorations.The
monastery settlement
is quite isolated from
the modern town of Λάμπουσα
(Lambousa, the resplendent),
and stands on the northern waterfront
of Cyprus.
The inclusion of the complex
into a military barracks in the
Seventies included the transformation
of some parts and
the addition of service structures.
In the analysis made during
the workshop, the one on
the masonry types was capable
in outlining the phases of construction
for various parts of
the original complex. The church
in itself is not suffering from
specific structural issues, even
if it has lost a large part of internal
finishing and artwork,
the massive walls and vaults are
still capable in showing an articulated
layout and interesting
architectural features. The situation
is a little worse for the
northern wing of the monastery,
which suffered a heavy structural
damage and was stabilized
with some scaffholdings.

SECOND WORKSHOP IN CYPRUS:
KYRENIA CASTLE
The second workshop in Cyprus
was held in the Kyrenia Castle,
which represents the main
historical architecture on the
waterfront of this area, presenting
a very articulated transformation
through time, evolving
accordingly to the changes in
weaponry technologies and the
wills of its different owners (Camiz
et al., 2016). The Kyrenia
Castle shows three main periods
of architectural development,
representing a significant example
of the evolution from a medieval
castle to a fortress developed
for using and resisting
more modern weapons (Scott
Petre, 2010). The three periods
traceable in the architecture of
the fortifications are Byzantine
(330-1192), Lusignan (1192-
1472) and Venetian (1472-1570)
(Enlart, 1899). The special position
of this fortification, with its
strategic importance, dominating
on the seafront, is underlined
by archaeological evidence
in the castle area, Indeed it Is
possible to refer to remains of
Roman mosaics and catacombs
that suggest the presence
of even earlier settlements. To
this archaeological presence it
is possible to match the “Kyrenia
Shipwreck”, which is the
common name indicating the
important finding of a ship from
the IVth century BC in the waters
in front of Kyrenia (Katzev,
1981). This important relic, representing
one of the very first
underwater archaeology interventions,
is currently visible inside
the castle museum (Katzev,
2008).
In both workshop cases, the digital
survey intervention was conducted
using a Z+F 5006h imager
3D laser scanner unit with
the integration of photogrammetries
for the most interesting
parts and artworks and to give
a more complete and detailed
consistency to the digitalization
of these two architectures. In
2014, the aim was to produce a
complete documentation of the
religious settlement with a proper
level of details, supporting
further reading and offering a
first complete description of the
Church and monastery. In this,
the collaboration with the local
archaeologists turned out for
the most positive results, with
an extended sampling of mural
stratigraphies then connected
to the pointcloud derived from
the lasergrammetry and helpful
in supporting the construction
phase hypothesis.
In 2018, Kyrenia Castle was extensively
surveyed with a specific
attention to the spaces of
relevant historical importance,
and with a specific series of
photogrammetry on the exhibited
hull from the shipwreck
and also on a specific mural
element. In fact, in the same
room where the ancient ship
is kept, the top part of the internal
wall shows a large part
of plaster characterized by a
series of graffiti representing
ships and boats (Şevketoğlu,
2017). In most of the situations,
assigning a date and correctly
identifying the ship type in the
graffiti is not a simple or certain
task. However, as they are
often on the walls of a building,
on castle cisterns or churches,
the building they are made on
represents the terminus post
quem, the date after which the
graffiti was made.
CONCLUSIONS
Therefore, in this case it is possible
to give only an estimated
date standing in a wide span of
time, probably between the XII-
Ith and the XVIth century. In the
same way producing an appropriate
photogrammetry of this
artwork was quite challenging.
The difficult light condition as
well as the vibrations coming
from the platform giving access
to the graffiti required some
specific shrewdness for completing
a well usable photogrammetry.
Following, the resulting

https://skfb.ly/oqFIQ) plus a video about the graffiti (https://youtu.be/Yqw1ZrdWH1A).
3D digital model allowed an accurate
tool for better studying and visualizing
the set of nautical representations
exploiting virtual light solutions
and then putting in evidence all the
traces still existing on the surface of
the plaster (Bertocci et al., 2020).
In addition to the laser-grammetry
survey of the caste, in the 2018 workshop,
it was possible to operate a
drone flight, which was a significant
contribution to the completion and
integration of the digital survey. The
UAV unit available was a DJI Spark,
equipped with a 12 Mp camera, conducting
a series of flights and then
producing a sub-selection of the
best 1303 shots, covering the roofs
and almost all the top parts of the
walls, making it possible to generate
an extensive, accurately detailed 3D
model of the entire exterior of the
castle and its adjacent area. The
workshop in the Kyrenia Castle was
the occasion to establish an operative
base of knowledge and to gather
a significant amount of data about a
castle that represents a challenging
monument in the Mediterranean scenario.
The first digitalization of this
fortification is the starting point of
a series of studies. In between, a
certain number of Master Degree
and Specialization Thesis which included
the development of an HBIM
for some parts of the castle (Capparelli
& Camiz, 2019). Among the
various studies, a specific attention
was addressed to proposals for a new
museum, encompassing a strategic
restoration plan and the improved
display of key artefacts, most notably
the Kyrenia Ship and multiple
graffiti, supported by contemporary
digital and virtual museum technologies
(Ceylanlı et al., 2019). The
historical value of the subject and
the technically advanced intervention,
mixed with professional and
academic competencies has brought
to a high-quality teaching moment,
capable of putting in evidence historical
values and specific features of a
valuable built heritage.

Abstract
This paper presents two workshops in Cyprus focused on documenting
and rethinking the use of historical built heritage: the Acheiropoietos
Monastery (2014) and Kyrenia Castle (2018). Using 3D laser scanning,
photogrammetry, and UAV surveys, the projects revealed multiple
construction phases, structural features, and historical layers. Special
attention was given to the Kyrenia Shipwreck and wall graffiti. The
resulting digital models supported architectural analysis, conservation
strategies, HBIM development, and museum enhancement proposals.
These workshops demonstrate how interdisciplinary approaches
and advanced digital methods can effectively study, preserve, and
valorize cultural heritage.

Urban digital survey in Galata/
Beyoğlu: remains of the genoese walls
and of a Caravansary/Bazar
by Roberta Spallone,
Marco Vitali, Doruk Peker,
Silvia Michelon
A multidisciplinary investigation
of Galata’s waterfront that
combines archival and
cartographic research,
architectural-historical study,
stratigraphic urban analysis,
and advanced metric digital
surveying. By linking diachronic
urban transformations to the
physical evidence of surviving
walls and structures, the work
constructs a coherent narrative
supporting conservation,
interpretation, and public
dissemination — an experience
presented and discussed during
the International Urban Design
Workshop.

Galata, also known as
Beyoğlu or Pera, is one
of Istanbul’s oldest
and most stratified districts,
it preserves a multilayered
historical texture, a key aspect
for understanding the urban
palimpsest of the Golden Horn.
The International Urban Design
Workshop “Urban Façade:
Istanbul Waterfront” took place
from March 23rd to 30th, 2019,
at the Faculty of Architecture
and Design, Özyeğin University
in Istanbul. The workshop was
coordinated by Alessandro
Camiz and Giorgio Verdiani in
collaboration with the Italian
Universities of Parma, Rome
“Sapienza”, Naples “Federico
II”, Firenze, Dipartimento
di Architettura, Politecnico
di Torino, Dipartimento di
Architettura e Design, and
Università Mediterranea in Reggio
Calabria, the workshop focused
on the architectural survey,
analysis, and redesign of selected
blocks along Galata’s waterfront
(Dixon, Verdiani, Cornell, 2017).
The workshop’s concept was
not to teach the participants
about design transformations

as arbitrary architectural
objects but bringing them to
see the urban elements as living
organisms within the continuous
formation of urban tissues
(Camiz, Carlotti, Díez, 2017).
The studied area represents an
important connection between
the seafront and the historic
sectors in Galata; it acts like
Istanbul's “urban façade” towards
the Golden Horn (Cuneo, 1987).
The workshop addressed issues
of contemporary Istanbul,
such as the replacement of
traditional urban tissues with new
constructions offering globalized
market and generic features
(Verdiani et al., 2019). Urban
growth demands substitution of
building types, this is a certainty
in any human settlement in any
age, thus, recent interventions
have often erased traditional
structures, disrupting continuity
with the past, and inserting alien
typologies or even gross in-style
replicas into consolidated contexts
(Dallegio D’Alessio, 1946). The
teams in the workshop were
guided in distinguishing between
two modes of transformation:
one based on evolutionary
systems, considered coherent
with a diachronic urban process,
and a disruptive one, aimed at
a shifting in the development
of creative contrasts with the
existing context (Caniggia, Maffei,
1979). The raw data collected
during the fieldwork formed the
empirical basis of subsequent
studies, despite occasional
local opposition. The campaign
proved successful in documenting
the built heritage and fostering
further research, including
master’s theses by Doruk Peker

(Politecnico di Torino, supervisors
R. Spallone, A. Camiz, M. Vitali)
and Silvia Michelon (University of
Florence, supervisors G. Verdiani,
A. Camiz). These works deepened
the analysis of Galata’s defensive
towers, the Beyoğlu urban
system, and the Caravansary/
Bazaar (Bordini, Cottini,
2019). The interdisciplinary
approach combined archival
and cartographic research,
architectural-historical analysis,
stratigraphic reading, and
advanced metric surveying,
linking diachronic urban
transformations to the physical
evidence of walls and related
structures, ultimately forming
a coherent narrative supporting
conservation, interpretation, and
public dissemination.
URBAN TRANSFORMATIONS OF
GALATA/BEYOĞLU
The topographical knowledge of
Constantinople and its adjunct
settlements is quite fragmentary,
and the genesis and morphological
evolution of Galata/Beyoğlu
(identified in the “Notitia
Urbis Constantinopolitana” as
Regio tertiadecima) remain
only partially reconstructed.
While the Ottoman epoch of
Galata is documented, earlier
chronological stages rely on more
limited evidence. Historically
significant contributions include
Dallegio D’Alessio’s 1946
reconstruction, Paolo Cuneo’s
analyses (1983–1987), and recent
studies on the Genoese presence
(Saĝlam, 2018). Wolfgang Müller’s
cartographic proposals (1993)
emphasize the Genoese walls as
mainly Byzantine, a perspective
partially echoed by Dewing’s
(2015) depictions that retain
the Galata Tower (erected
under Genoese administration
in 1348) as the most identifiable
medieval landmark. The
diachronic reconstruction
hypothesizes successive phases:
the initial Megarean colony,
the Roman expansions under
Constantine and Honorius,
and the later Justinian urban
reforms. Corroborating evidence
derives from sparse documentary
sources, archaeological indicators
(mostly hydraulic infrastructures)
and orientation analysis of
current urban patterns. The
integration of these data
permitted the production of a
working topographical model
localising primary components
of the Roman and Byzantine
settlement system in the Galata
area, framing the fortifications
within a broader urban evolutive
trajectory.
DIGITAL SURVEY OPERATIONS
Documenting fragmented and
altered fortifications requires
meticulous planning to guarantee
precision, comprehensiveness,
and interoperability of results.
The metric campaign adopted
a Leica Geosystems ScanStation
C10 3D Laser Scanner (time-offlight),
a unit with a declared
working range up to 300 meters
and point accuracy in the order
of a few millimetres at short
distances (Bini & Bertocci, 2012;
Bianchi et al., 2016). The scanner
records a full panoramic sweep,
producing point clouds whose
density was configured to roughly
one point per centimetre at a
10 metres working distance for
the majority of scan stations.
The device’s integrated imaging
system captured photographic
data for colour-mapping the
point cloud without introducing
parallax distortions, enabling
better reading of the fronts
in their overlays and material
identification, rendering
masonry, metal fixtures, fissures,
voids, and displaced fragments
with high visual fidelity. The
overall scanning time took three
days, covering an area of about
40.000 square metres with 98
scan stations, gathering about
one billion of points. For the
specific subject of the towers
the fieldwork comprised 40
scans: 14 stations concentrated
around the first tower (formerly
subjected to industrial use), 10
taken from a distance around
the second (which was at that
time in complete abandon and
without any possible direct
access), 15 within the sector
where recent building additions
and a restaurant about the wall
was still allowing interesting
parts of original masonry work
to emerge, and one elevated
rooftop scan to enhance intersessions
alignment. Restricted
access and hazardous conditions
prevented comprehensive
interior scanning; however,
exterior apertures and partial
interior surveys permitted metric
estimations of wall thickness
and notable internal features.
Data alignment exploited longrange
tie features, including the
Galata Tower and other distant
rooflines, to integrate sectorial
point clouds into a coherent
global model suited for CADbased
restitution using Autodesk
Recap and AutoCAD.
The focal artifact is the second
tower located southwest of the
Galata Tower: a U-shaped plan of
approximately 9.80×7.70 metres
and a height near 16 metres.
The circular facade confronts a
northern courtyard (currently a
parking area), while the southern
side intersects the city wall

adjacent to the local St. Peter’s
Church. Observational evidence
indicates foundational contact
with bedrock, attributable to
historical soil lowering that
gradually exposed foundational
elements. Surface traces,
remains of plaster, and imprinting
phenomena attest to successive
additions and demolished
adjacent structures; presently,
a marginal warehouse remains
adjacent to the southwestern
facade. Successive inappropriate
adaptations (fenestration
insertions, intermediate floor
insertions, non-original claddings)
have undermined structural
coherence, generating cracks,
projection of beams, and
other deterioration signs. The
absence of a weatherproof roof
accelerates material decay.
Given the incomplete internal
metric data, interpretative
restitution relied on the synthesis
of the lasergrammetry taken

in the context taken from the point
cloud, and view of the point cloud
taken in the restaurant exhibiting a

on the external and with few
scan stations operated in the
interiors. So the profile of the
walls was considered as an
offset of the external profile
getting a better accuracy using
the integration of internal
traditional measurements, on-site
photography, and comparative
analogies with better-preserved
typologies. In the case of
the Caravansary, there is the
presence of a classic old market
space like those found in Turkey
and across the Middle East (Khan
Madel, 1988). Currently, this
specific one is used by a certain
number of hardware shops
and technical services. Some
exceptions include a painter's
studio and a bicycle shop. The
robust structure, with thick walls,
does a good job in preserving the
original layout of the building.
Changes to the architectural
aspects have been small, mostly
involving the adding of features or
cutting into the walls for updating
the cooling, electrical, and
plumbing systems. However, little
focus is placed on keeping up the
external, internal, and common
areas. The documentation of
the Caravansaray was done
on a partial lasergrammetry
integrated and completed by
photogrammetry.
The overall result was perfectly
functional for analysing and
studying the layout and the
original features of the building,
especially the use of arches and
the geometry of the planning grid,
allowing a possible attribution
to Mimar Sinan himself or to
his professional circle (Verdiani
and Michelon, 2025). For these
built heritage architectures,
horizontal and vertical slices
of the point cloud produced
accurate profiles used to derive
plans, elevations, and sections
that were subsequently refined
through AutoCAD after Recap preprocessing.
This process yielded
a comprehensive yet critically
annotated graphic dataset
that records both measurable
geometry and conjectural
reconstructions based on
archaeological reasoning and
stratigraphic reading. Graphic
restitution functions as both
documentary archive and
an operative instrument for
conservation planning. The
restitution adopted a 1:50 scale
which is adequate to represent
material texture, door and
window frames, and principal
forms of degradation: structural
fractures, lacunae, material
washouts, detachments, and
biological colonisation. Selection
of horizontal section planes
responded to the identification of
original and secondary openings
(including occluded voids)
and to the placement of thin
interior slabs surveyed by direct
inspection. Plans at varied levels
were produced to characterize
vertical stratification; vertical
sections articulate masonry
discontinuities, revealing
bonding changes, insertion
planes, and back-elevation
relations. Elevations derived
from orthophotoplanes were
supplemented by in-situ eidotypes
and direct measurements.
The resulting plates synthesise
geometric accuracy with
thematic mapping of materials,
stratifications, and decay
patterns, and were designed to
be intelligible for conservation
professionals, structural
engineers, and curators. These
drawings emphasize vulnerability
hotspots and inform prioritised
conservation interventions,
underpinning the proposal for
an open-air museum focused on
urban memory and accessible
interpretation.
CONCLUSIONS
Accurate surveys and systematic
documentation of neglected
architectural heritage are of real
value, enhancing the building
condition, enabling multi-user
access to metric data, and giving
a starting point for restoration,
reuse, and virtual reconstruction.
Indeed, in the case of total loss,
drafts and detailed drawings
remain valuable for at least
partial virtual restitution and
scholarly analysis. Digital
documentation enhances the
exchange between different
professions-from architectural
historians to conservation
engineers-and opens paths to
public engagement, education,
and sustainable tourism. The
description of masonries,
morphological definitions, and
stratigraphic interpretations
obtained during the Galata case
study enable new insights into
the different construction phases
and provide a basis for targeted
interventions. Considering the
high risk of loss and progressive
alteration of the Galata area, the
documentation helps to prevent
the indiscriminate conversion
of it into an homogeneous
sector dominated by transient
commercial activities.

Abstract
Galata, one of the most historically layered districts of Istanbul, represents a critical site for understanding the
urban palimpsest of the Golden Horn. The research focuses on the analysis and documentation of selected blocks
along the Galata waterfront, investigating the relationship between surviving defensive structures, later architectural
additions, and contemporary transformations affecting the district. The study adopts an interdisciplinary
methodology combining archival and cartographic research, architectural-historical analysis, stratigraphic
urban reading, and advanced metric digital surveying through 3D laser scanning. The resulting point clouds, orthophotos,
and CAD restitutions enabled the reconstruction of diachronic transformations and the identification
of alterations, discontinuities, and degradation patterns within key architectural artifacts, including the second
tower of the fortification system and the historic Caravansary complex.
The integration of empirical survey data and historical sources facilitated the development of a coherent interpretative
narrative linking urban growth processes to the physical evidence of masonry structures and spatial
organization. This approach contributes to understanding the dynamics through which traditional urban tissues
have been replaced by new construction driven by globalized market logic, often compromising typological continuity
and authenticity. The outcomes support conservation-oriented strategies, promote informed decision-making
for restoration and reuse, and provide a framework for future research and public dissemination. The work,
presented and discussed during the International Urban Design Workshop “Urban Façade: Istanbul Waterfront”
(2019), highlights the value of accurate documentation as a tool for preserving memory and guiding culturally
responsible urban transformation.

Time fragments: design proposal for

conducted by Zemastek in
cooperation with Giorgio
Verdiani, was the foundation
for the design developed
during the international

workshop Architecture and
Archaeology. Theodosius’
Forum, Istanbul. The
design proposes the
partial demolition of the
Şimkeşhane building,
defining a new excavation
of the area of the forum,
revealing the ancient Mese.
The project also includes a
small pavilion as the gate
of the archaeological area,
with an Analogical and

Theodosius’ arch.
PRELIMINARY NOTES ON THE
TOPOGRAPHY OF THEODOSIUS'
FORUM IN CONSTANTINOPLE
We conducted a preliminary
research on the topography of
Theodosius’ forum in order to
define a credible hypothesis on
its form and location. To define
the plan (fig. 1) we examined the
archaeological findings of the
area, the main historical sources,
and the diachronic sequence of
cartographical representations of
the area starting from Giovanni
Andreas Vavassore, Byzantivm
sive Costantineopolis, 1535.
The comparative analysis of the
monuments described in the
Notitia Urbis Constantinopolitana
for the regions VII and VIII of
Constantinople allowed us to
establish the location of the
Basilica Theodosiana on the
northern side of the Mese.
We identified the Thermae
Carosianas on the north with
the great Nymphaeum at the
end of Valens aqueduct, and the
porticus connecting this forum
to the other one dedicated to
Constantine. We defined the
location of the tortile column
of Theodosium, by comparing
Vavassore’s plan, where it is
depicted still standing, with
other later plans such as the
Alman Mavilleri (1913-1914). This
hypothesis seemed sufficiently
coherent with the description
of the forum given by the Patria
Constantinopoleos.
“About Taurus. That in the
Taurus there is a stele of the
great Theodosius, but it was
formerly of silver, Although he
received those from the nations
who came, there were former
palaces there and a palace of
20 ArcheomaticA N°3 2025

the "Romans", although in the
so-called "Alonitzin". On top of
the great column Theodosius was
placed, and his sons, Honorius
on the stone arch to the west,
and Arkadius on the stone arch
to the east, above the arches of
the great tetradesians columns.
And in the middle of the court
is a great horse, whom some
call Jesus the son of Naeus, and
others Bellerophon, who came
from the great Antioch. And the
four-sided stone horse is covered
with the history of the city's end,
of the future gates of this city.”
(Preger, 1901).
The plan was essential for the
design. Since the design intends
to partially re-establish the forum
within the surrounding most
central area of Beyazit and its
monuments and urban tissues,
it was necessary to outline our
interpretation of what the forum
and its monuments used to be.
Designing within an archaeological
area, in our opinion, is almost
impossible without a detailed
survey of the context. The needed
survey is usually multiscalar,
operating at the territorial scale,
the building scale, and at the scale
of the architectural fragments.
Architectural fragments which
in this case are abundantly lying
on the sidewalks without any
indication of their importance.
We are very thankful to Fahrettin
Doğan Tekin (Zemastek Yapı
İnşaat Restorasyon) for the LIDAR
survey of Theodosius’ forum and
to Giorgio Verdiani (University
of Florence) for the scientific
coordination of the LIDAR survey
and the photogrammetric survey
of the architectural fragments.
Without their contribution, it
would have been impossible for
us to define a credible design
proposal. If we could generalise
this principle, we should say that
in an archaeological area, survey
and design must walk together, at
the same time, instead of being
two separate and independent
actions as usually happens.
Upon this principle of scientific
cooperation, we have based the
action of more than 10 years of
activity within the workshops
and summer schools organised
by the International Network for
Architecture and Archaeology.
INAA is an international network
of scholars, researchers and
practitioners who in the past
10 years have been working
in the field of Architecture
and Archaeology. Each year it
organises a summer school open
to students of architecture,
restoration, archaeology
and design. https://www.

THE ARCHAEOLOGICAL PARK
OF THEODOSIUS IN ISTANBUL:
DESIGN PROPOSAL
Currently the only visible remains
of the forum are two bases of the
columns of the monumental arch,
and a collection of architectural
fragments, mostly belonging to
the arch as well, scattered along
the sidewalk of Ordu Caddesi.
The fragments consist mainly in
marble elements belonging to
the architectural order of the
arch, very singularly a Heracles
Corinthian. The columns had
notches on the shaft, just as
Heracles’ classical statues
depicted the club, and to
enhance this symbolism, the
column’s imoscape displayed
the hand of the mythical figure
sculpted. The arch was built to
hold the statues of the two sons
of Theodosius, Arcadius and
Honorius, and perhaps it was
meant to express a menace to the
population in times of trouble.
The bases and the fragments are
the result of an excavation, that
was possible after the partial

demolition of Şimkeşhane, by
British archaeologists Stanley
Casson and David Talbot Rice
(1927-1928) leading to the
discovery Theodosius triumphal
arch (A.M.W. 1929). After the
excavations, there was a partial
anastylosis of some columns on
top of the bases, still visible,
the side of the Şimkeşhane was
reconstructed in order to function
as a market again, and another
base is currently visible in one
of the shops on the ground floor.
After the understanding that
most of the Şimkeşhane as we see
it is not the original building but a
modern reconstruction, we came
to the conclusions that it could be
possible to demolish it (partially)
in order to establish a wider and
deeper excavation capable of
uncovering the pavement of the
forum and the Mese. We based
the design on this assumption
and on a number of key design
concepts such as time, limit/
enclosure, levels, entrance,
fragments, public space and
narrative. After the subtraction
provided by the proposed
archaeological excavation our
proposal included the partial
anastylosis of the columns over
their bases, a small pavilion
providing the entrance to the
archaeological area on the street
level, a vertical distribution to
reach the archaeological level,
small archaeological laboratories
and deposits on the lower lever.
Within the entrance gate, a glass
with the printed reconstruction
of the arch would provide to the
visitor the analogic augmented

the lower level, we designed a
path for the visitor, displaying
on properly designed stands
with captions, the remaining
fragments. We conceived the
retaining walls of the excavation,
as well as the pavilion itself, as
entirely covered with a green
wall system.
CONCLUSIONS
Not only as we mentioned,
the digital survey of the
premises were essential for the
development of this proposal, but
also the deep understanding of
the site and the ongoing identified
process. A conformal design is
based upon the understanding
of all the phases, including
the first construction, the
collapse following the historical
earthquakes, the subsequent
ottoman buildings constructed
atop, but also the modern
excavations and restorations. The
knowledge of these phases in an
archaeological area is the starting
point for a properly conceived
design, a design conceived as
the continuation of an identified
ongoing process.

Priene and Magnesia ad Maeander:
main architectures and urban morphology
by Görkem Kökdemir, Pelin Yoncaci Arslan
Despite differences in scale, origin,
and topographical context, Priene
and Magnesia ad Maeander share
fundamental planning principles rooted
in the Hippodamian urban model,
characterized by orthogonal layouts
and a clear hierarchy of civic, religious,
and residential spaces. The impact of
environmental dynamics, including
seismic activity and fluvial processes,
has a significant impact on the urban
evolution of both cities. Recent digital
survey campaigns using photogrammetry
and 3D laser scanner technologies in
the present time are essential tools for
documenting, analysing, and interpreting
these complex archaeological contexts.
The cities of Priene and
Magnesia ad Maeander
represent two important
examples for the study of urban
development, the relationship
between environments and
settlements, and architectural
expression in the Hellenistic
area, in a territory later known
as Asia Minor. Both communities,
situated in the Maeander valley
of western Anatolia, reflect the
dynamics of power in the aftermath
of Alexander the Great’s
conquest and the subsequent
events of his sudden and premature
death, through the Roman
conquest, subsequent transformation
and abandonment. The
two cities have different origins,
scales, and urban trajectories,
but both share a series of
events in which the local Greek
communities negotiated autonomy
and identity within a rapidly
transforming geopolitical
environment until the Roman
intervention. They also share a
series of natural disasters and
transformations that should
impress and prompt reflections
on how an odd environmental
transformation may bring ruin
and chaos to formerly wealthy
settlements.
Their archaeological remains,
particularly the well-preserved
urban fabric of Priene and
the monumental sanctuaries
of Magnesia, offer opportunities
to read and interpret the
urban setup originally defined
by the civic ideologies of Hellenistic
cities and later adapted,
expanded, and transformed in
the Roman period. Both cities
share the specific urban rational
layout defined by Hippódamos
of Miletus, with rigorous planning
and a coherent integration
of architecture, public, social,
religious, and private spaces
into a system that would shape
and influence the future developments
for centuries.

THE URBAN CONTEXT IN PRIENE
Priene is situated on the southern
slope of Mount Mykale, overlooking
what in antiquity was
a gulf opening into the Aegean
Sea. By the Hellenistic period,
however, the silting of the Maeander
had already begun to
push the coastline westward,
thus gradually detaching Priene
from the seashore that had once
defined its economy and strategic
importance. The city was
architecturally replanned in the
fourth century BCE, providing
a model for a rational, orthogonal
urban plan organized into
a series of large terraces. The
sloppy topography imposed serious
constraints that required a
specific architectural attention,
producing one of the clearest
surviving examples of Hellenistic
city planning.
Priene is a paradigmatic example
of urban planning of that
time (Wycherley, 1945). Its
street grid, which recognizes
Hippodamian principles, organises
the city into regular sectors
aligned with the cardinal directions,
though subtly adapted
to the mountain slope. Public
buildings, including the Agora,
the Bouleuterion, the Prytaneion,
and the Theatre, share
a coherent architectural vocabulary,
offering specific solutions
while remaining consistent with
the city’s layout. The Temple of
Athena Polias, designed by the
architect Pytheos, stands as the
city’s principal monument and
embodies the refined Ionian tradition.
It was dedicated by Alexander
the Great during his campaign.
The temple symbolised
the city’s religious devotion and
its strategic engagement with
broader geopolitical forces. At
the same time, the city suffered
from the compromise of
the harbour; its economy likely
faced serious problems from the
progressive silting of its port,
which probably led to a shift
in efforts toward agriculture,
craftsmanship, and cultural
institutions, helping realign
productive activities. At the
same time, the occurrence of
some unfortunate events, such
as strong earthquakes and occasional
rocks falling from the
mountain’s sides, certainly created
difficult situations. After
its final abandonment, the city
preserved a substantial amount
of its original architecture; the
laborious work required to
remove blocks probably made
the ruins less interesting for

reuse, leaving them to wait for
centuries before being rediscovered
and excavated.
The German archaeological
campaign at the end of the
XIXth century brought to light
the main buildings and revealed
the urban pattern. Intervention
by French and English missions
led to the discovery and expansion
of the excavated areas. The
present Turkish activity led by
Ibrahim Hakan Mert is mainly
oriented to maintenance and
specific exploring interventions.
THE URBAN CONTEXT IN MAG-
NESIA AD MAEANDER
Magnesia ad Maeander, instead,
occupied a lowland setting on
the south bank of the Maeander
River, several kilometres East
of Priene. Unlike its neighbour,
Magnesia developed in a flatter
environment that facilitated
expansion and allowed
the construction of monumental
sanctuaries and civic spaces
on a scale beyond the capacity
of Priene’s terraced hillside.
Although less well preserved,
Magnesia’s remains, especially
the Artemision and the stadium,
demonstrate how a city with
strong regional connections
and external patronage could
reshape its urban environment
to communicate prosperity,
cultural refinement, and political
significance. Both cities
navigated the shifting imperial
administrations of the Hellenistic
period. Initially subject to
Persian authority, they were
successively incorporated into
the realms of the Diadochi,
most notably the Seleucid and
Attalid kingdoms. The interests
of these monarchies, whether
expressed through benefactions,
administrative oversight,
or military imposition, significantly
influenced the development
of the two communities.
Yet both Priene and Magnesia
retained strong civic identities,
expressed in epigraphic
culture, religious activity, and
the maintenance of traditional
institutions.
Magnesia’s urban organization is
less comprehensively preserved,
but archaeological evidence
suggests a dynamic and ambitious
program of monumental
construction, particularly
during the second century BCE,
when the city benefited from
the patronage of the Attalid

dynasty and later from Roman
domination. The Artemision of
Magnesia, dedicated to Artemis
Leukophryena, was celebrated
in antiquity as one of
the most impressive temples
in Asia Minor (Dunand, 1978).
Designed by the architect Hermogenes,
the building introduced
the pseudodipteral plan,
a significant innovation that
influenced temple architecture
throughout the Hellenistic and
Roman worlds. The sanctuary
served not only as a religious
focus but also as a symbol of
civic prestige, emphasizing the
city’s role as the guardian of a
renowned cult and host of the
Leukophryena festival, which
attracted participants from
across the Aegean. The urban
fabric of Magnesia was further
enhanced by its stadium, still
well preserved (notwithstanding
a series of significant disruptions),
and by numerous public
buildings. The scale and the
quality of these structures show
how a city positioned inland,
away from the major coastal circuits,
could nevertheless thrive
through agricultural wealth and
strategic alliances.
The city was economically
shaped by its position in the
Maeander valley, a fertile region
that produced agricultural surpluses
and supported a network
of overland and fluvial
trade routes. Magnesia probably
enjoyed more sustained
prosperity than Priene, due to
its more adaptable geographical
position and the benefits of
royal patronage. Its sanctuaries
attracted pilgrims and visitors,
adding a religious dimension to
the local economy. The recent
archaeological discovery demonstrates
the reuse and insertion
of buildings over a wide span
of time; the final abandonment
caused the city to completely
get lost in the mud of the floods
until its rediscovery by French
and German archaeological missions
at the end of the XIXth
century (Humann, 1904). After
almost a century, the interventions
resumed in 1984 with a
mission led by Orhan Bingöl,
which identified new sectors
and improved the urban layout
(Bingöl, 1998). The richness of
the discoveries yet to be made
is confirmed by ongoing archaeological
work led by Görkem
Kökdemir, which is unearthing

vast, complex areas, limiting
the still-present menace of
floods, and reconstructing significant
parts, giving visitors
a better opportunity to read
the original aspects.
DIGITAL SURVEY CAMPAIGNS
The digital survey interventions,
operated in 2022
(Priene), 2024 and 2025
(Magnesia) allowed the gathering
of both architectural
and urban data, defining an
archive previously usable for
further research and study
works. The interventions
in 2022 and 2025 were conducted
using 3D laser scanner
units, terrestrial and aerial
(drone/UAV) photogrammetry
(the intervention in 2024
was based only on photogrammetry
of the stadium and of
some sparse findings). In this
way, the level of detail gathered
may range from the city
scale to the single building to
the specific detail, enabling a
continuous reading in a real
interdisciplinary mode. This
was widely achieved through
the use of 3D laser scanner
units with a consistent operating
range and high accuracy,
UAVs combined with terrestrial
image capture, and terrestrial
photogrammetry with
varying distances for specific
details. In this way, we have
obtained different densities in
describing architectural parts
and artworks while maintaining
the overall context without
increasing computational
time or model complexity.

Abstract
Priene and Magnesia ad Maeander constitute two emblematic case studies
for investigating Hellenistic urban planning, architectural form,
and the relationship between cities and their environmental settings
in western Anatolia. Both settlements developed within the Maeander
valley during the Hellenistic period, under complex political and
cultural conditions following Alexander the Great’s conquests, and later
underwent significant transformations during Roman rule before
abandonment. Despite differences in scale, origin, and topographical
context, the two cities share fundamental planning principles rooted
in the Hippodamian urban model, characterized by orthogonal layouts
and a clear hierarchy of civic, religious, and residential spaces. Priene,
founded on the steep slopes of Mount Mykale, represents one of
the most complete examples of an orthogonal urban system adapted
to a challenging terrain. Its preserved street grid, domestic quarters,
and monumental buildings, including the Temple of Athena Polias,
reflect the ideological coherence of Hellenistic urbanism. Magnesia
ad Maeander, established in a flatter landscape, developed on a larger
scale, enabling the construction of extensive monumental complexes
such as the Artemision and the stadium, which expressed civic identity
and regional importance. The impact of environmental dynamics,
including seismic activity and fluvial processes, have a significant
impact on the urban evolution of both cities. Recent digital survey
campaigns using photogrammetry and 3D laser scanner technologies
in the present time, are essential tools for documenting, analysing,
and interpreting these complex archaeological contexts.

In the natural context, the
human being has always looked
for places to live in safety.
Shelters against predators,
protections from the cold and the
rain, the realization of houses to
live in can be seen as an outcome
of a research of protection.
At a wider scale, the urban
settlements, the villages and
the cities, have represented the
association of more individuals
into stronger societies.
The anthropization of the
environment has been, in history,
the response to the human need
to accommodate nature to their
will, passing from an hostile place
to an Eden garden providing foods
and supplies.
Nonetheless, the unequal battle
between humans and nature has
revealed on many occasions the
power of planet Earth, capable
of destroying rapidly what has
required years of work. Floods,
storms, earthquakes, volcanos
are the most catastrophic ways
to point out the ephemeral
presence of human settlements
in the world.
In history, the battle for ancient
civilisations was harder than
nowadays. Despite the more
famous events, e.g. the Pompeian
destruction occurred in 79 BC.,
many minor episodes have led to
the collapse of ancient societies.
In this context, earthquakes are
within the most dramatic natural
hazards. The unexpected ground
shaking is causing the collapse
of the constructions, leading
to death and injuries. In the
unfortunate cases, this can bring
further destruction. The most
iconic and well-known example is
given by the Lisbon earthquake of
1755; after the mainshock, which
led to damage and collapse of
constructions, fires started in the
houses, while a tsunami hit the
lower part of the city. When the
fury of nature stopped, around
85% of the city was destroyed,
with around one third of the
population’s death.
Dealing with the topic, when an
urban settlement was devastated
by an earthquake, in many cases,
the easiest way to re-start was
to relocate the city to another
place.
This is something still documented
in recent years (e.g. the case
of Gibellina, in Sicily IT), as in
ancient times.
NATURAL AND HUMAN
FURY IMPACTING PRIENE
In minor Asia, the history of
the city of Priene, its ascent
and decay, are a testimony that
reminds the perseverance of
human beings to realize their
spaces and protect them against
the force of nature and the
changes of the world.
According to tradition Priene was
founded in the eleventh century
BC by Aepytus, grandson of the
legendary Athenian King Codrus,
in association with the Theban
Philotas.
Priene represented an important
town in Ionia and according to
ancient historical sources such as
Pliny the Elder and Strabo, the
city was struck by a devastating
earthquake in the fourth century
BC. The event caused significant
damage, leading to the collapse
of many buildings.
Priene was destroyed not only
by natural disasters but also
by human activity, enduring
repeated attacks from the
Cimmerians, Lydians, and
Persians. Following the Persian
Wars, it joined the Delian League
under Athens, which intervened
in 441 during a dispute between
Miletus and Samos over control of
Priene. (Cook & Spawforth, 2016)
However, it appears that Priene
was relocated to a different site
during the time of Alexander the
Great; he himself visited around
334 BC, and it was then that the
transfer took place, reportedly
accompanied by an inscription
granting an exemption from
tribute. The new city was built
on a series of terraces along the
steep slope of Mount Mycale,
facing Miletus and overshadowed
by its acropolis on Teloneia Hill.
This second Priene, relocated
about 3.7 km from the original
city (roughly twenty stadia), is a
prime example of urban planning
and the best surviving instance
of a town from this period.
With its walls stretching along
a broad ridge, descending from
the steep face of the Teloneia
toward what must have been the
estuary of the Maeander, the new
settlement featured a systematic,
symmetrical grid layout based
on the Hippodamian grid plan,
designed to accommodate a
population of perhaps 5,000 (Fig. 1).
The most prominent building,
towering above a lofty terrace
with a Doric Stoa, was the
sanctuary of Athena Polias.
It was designed, according
to Vitruvius, by Pytheus, the
architect of the Mausoleum at
Halicarnassus. Initially dedicated
to Alexander the Great (though
not completed at that time), it
was later rededicated to Athena
and Augustus. The shrine was
adorned with various sculptural
groups dating from the late
fourth century BC to the early
second century AD. In front of
the temple stood a monumental
altar designed by the renowned
Hermogenes of Priene (c. 150
BC), of which little has survived.
(Cordan & Besgen, 2022)
Research has shown that the
vulnerabilities and resilience
of Priene's inhabitants shaped
their responses to seismic
activity, influencing the city's
reconstruction efforts after
major earthquakes recorded in
various periods, including 68 AD
and 1653. (Altunel, 1998; Topal,
2019; Mozafari et al., 2019)
These discussions highlight
the interplay between cultural
heritage, societal structures,
and technological advancements
in understanding and mitigating
the impacts of disasters.
DIGITAL TECHNOLOGIES
IN DISASTER DOCUMENTATION
Despite advancements
in documenting Priene
digitally, challenges remain,
including the need for
standardised methodologies
and collaborative approaches
among interdisciplinary teams.
The integration of emerging
technologies with traditional
archaeological practices offers
promising pathways to ensure the
sustainability of cultural heritage
while addressing ethical concerns
about accessibility and community
engagement. (Giovannini et al.,
2023).
Digital technologies are vital for
documenting and safeguarding the
cultural heritage of archaeological
sites, especially during disasters.
As disasters become more
frequent and severe, the ability
to monitor, manage, and protect
architectural heritage has become
increasingly important. These
technologies enable the creation
of digital archives that not only
record the current conditions of
sites but also support disaster
response and recovery efforts
(Mendoza et al., 2023).
One of the primary methods used
in disaster documentation is 3D
scanning and photogrammetry.
These techniques enable the
collection of highly accurate data
for the virtual reconstruction
of archaeological artefacts
and sites. The combination of
historical records with 3D outputs
improves understanding of site
contexts and helps in conserving
fragile items that might be
threatened by environmental
damage or disasters. The use
of these technologies enables
the creation of detailed digital
models that serve as references
for future preservation and
restoration efforts. (Maietti,
2023).
Alongside technical
documentation, digital
technologies support the
creation of virtual exhibits and
online databases. Platforms like
Europeana, the Smithsonian's
Digital Collections or commercial

ones like sketchfab offer access
to millions of digitised items,
including artefacts threatened
by disasters. By making these
resources available online,
researchers and the public
can engage with and study
objects that may be physically
inaccessible due to fragility or
location. (Champion & Rahaman,
2020).
DIGITAL TECHNOLOGIES APPLIED
TO PRIENE RUINS
Digital preservation not only
helps protect cultural heritage
but also ensures that knowledge
about these artefacts is shared
globally. The methodologies used
in the study of Priene involve a
systematic literature review
and bibliometric analysis based
on previous German research.
One of the main challenges
is balancing technological
innovation with the authenticity
of cultural narratives. The risk of
oversimplifying complex histories
to engage broader audiences
requires a careful approach to
digital preservation.
As digitisation projects continue
to digitise artefacts and
create virtual exhibits, best
practices for data management
must be established. Within
digital acquisition in Priene,
an integrated workflow was

implemented to acquire and
disseminate Priene monuments
digitally, demonstrating how
digital technologies can transform
the understanding, preservation,
and communication of
archaeological heritage (figs. 2-3).
These approaches include the
practical storage of raw collection
data, processed files, and related
metadata.
The point clouds obtained (raw
data), document large-scale
survey campaigns using laser
scanning, UAV and terrestrial
photogrammetry. 3D models
(processed files) allow the analysis
of major structures such as the
Doric Stoa terrace wall and the
Theatre, revealing construction
methods, structural behaviour,
and patterns of historical damage,
particularly from seismic events.
(Giovannini et al., 2024)
Archival research (from online
platforms, e.g., iDAI.world
repository or Census database)
and 360° images and virtual tours
provide remote, georeferenced
access to Priene’s artefacts. This
includes not only monuments but
also marble statues now housed
abroad, showing how digital
acquisition, object biographies,
and virtual tours can virtually
reunite objects with their original
context (fig. 4). (Verdiani &
Giovannini, 2024)
By integrating reality-based
models, historical documentation,
semantic structuring, and online
dissemination platforms, the
projects demonstrate how
digital tools validate and expand
prior archaeological knowledge,
support conservation planning,
and make cultural heritage more
accessible to specialists and the
general public.
As researchers continue to
explore the complexities of the
past, Priene stands as a testament
to the enduring relationship
between humanity and nature,
illuminating the lessons learned
from the past as we face the
uncertainties of the future.

Magnesia ad Maeander,
the Stadium, a matter of scale
by Giorgio Verdiani, Francesco Tioli, Görkem Kökdemir
The Stadium of Magnesia
represents a typical
large architecture once
dedicated to sport
activities, the size and
the relationship with its
environment, together with
the remaining details, make
it a specific and fascinating
survey subject
The Stadium of Magnesia ad
Maeandrum is situated in
the southwest sector of
the ancient city, it was built in
the Ist century AD exploiting
the slopes between two hills
oriented according to a North-
South axis. It was built with
the logic of a great structure,
with a track length of about
189 meters (638 Roman Feet)
and an estimated seating
capacity of 30,000 spectators,
it represents a significant
monumental structure in the
region and for that age. It was
made on the border of the main
historical settlement, thus it was
thought as strictly connected
to the city of Magnesia, as a
high quality architecture. Its
archaeological investigations had
taken a significant step forward
since 2008, with methodic
excavations, unearthing the
stands and starting the discovery
of its architectural parts and
functional artworks. In time,

the stadium had suffered from
multiple old damages caused
by seismic activity, terrain
movements, floods, vegetative
overgrowth, and the looting of
stone for reuse and for lime
production, but even after such
a long series of small and great
disasters the stadium remains
one of the best-preserved
examples in Anatolia and the
wider Mediterranean world.
Extensive excavation efforts,
particularly those concluding in
2018 regarding the sphendone
(the curved end of the stadium),
have revealed architectural
properties that distinguish
this structure from known
contemporaries (Bingöl, 2020).
The reason for the creation of
such a complex and extended
architecture may be found in
its initial dedication to serve as
the venue for the Leucophryena,
a major festival dedicated to
Artemis Leucophryene (Bingöl,
2005). In this event a series
of games were used to take
place, they comprised the three

primary branches of gymnastics
(athletics), equestrian events
(mostly horse and chariot racing)
and musical competitions. It
is of some interest reflecting
about the fact that the musical
contests were intended for the
Theatron, which appears as an
incomplete building, which may
suggest that the stadium may
have served a multi-purpose
function. Overall this last
feature was not influencing
the architectural choices in
planning this architecture,
which appears oriented to host
efficiently equestrian activities
and multiple parallel sport
exhibitions or matches.
THE STADIUM ARCHITECTURE
The architecture of the
stadium features three main
technical installations for the
administration of races: the
start structure, located at the
North end, features a complex
arrangement of 24 pillars and
arches. Excavation of the
postaments (bases) revealed
slots for a mechanism designed
to ensure a simultaneous start
for all the runners in the race.
The second is the finish line:
Located 189 meters South of the
start, the finish line is marked
40 ArcheomaticA N°3 2025
Cultural Heritage Technologies 41
by four double-prismatic freestanding
pillars. The spaces
between these pillars likely held
ribbons to determine the victor.
The third Structure is
represented by the herms,
which are the finish line pillars
decorated with double busts,
featuring both bearded and
clean-shaven figures. These
likely commemorate famous
athletes, or they may symbolize
a philosophical reflection on
the duality of victory and life
somehow recalling the "Two-
Faced Janus" (Janus Duplex)
allegorical figure (Casini, 2018).
While the Leucophryena included
equestrian events, architectural
analysis suggests the stadium
was ill-suited for heavy chariot
racing. The presence of fragile
free-standing pillars and Herms
at the finish line would have
posed a severe collision risk
during the high-speed turns
required in chariot races. It
is therefore posited that the
stadium hosted only symbolic
or light equestrian events,
while it is possible to suppose
that full-scale chariot races were
likely held in a separate, as-yetundiscovered
hippodrome. The
stadium represents a multi-scale
architecture, even in ruins the
specific features in Magnesia
demonstrate how the massive
body of the main building is
connected to the landscape
itself, It is a sign and a trace
visible from the distance and its
“U” shape create a spectacular
entrance from the side of the
city. At the same time it soon
varied its scale at the dimension
of the details, with well defined
particular use of rich materials,
like multicoloured stones and
marbles, creating a constant
attention and curiosity in the
visitor and a fascinating passage
from territorial scale to minimal
scratches on stones.
The stadium contains also a
significant epigraphic archive,
presenting a series of epigraphy
elements connected to the
ancient social stratification
of the city. This is manifest
with inscriptions found on seat
backrests and podium façades
offering insights into the social,
economic, and political levels of
the inhabitants of Magnesia.
But there are also writes that
testify inter-city relations:
an inscription on the podium
marks a section reserved for the
"Ephesians," indicating a formal
protocol for hosting spectators
from rival or neighboring cities.
Other inscriptions tell about
professional associations, like
those on the 11th, 12th, and 13th
cercises, while specific writings
name unions and associations.
These areas functioned not
only as spectator seating but
as designated spaces for guild
meetings. In the end, the
epigraphic writes testify the
elite patronage: specific rows
were allocated to prominent
families. For instance, the
"Council of Elders" and members
of the Claudian family held
reserved seating.
In the variety of sculpted writes,
a particularly notable inscription,
Mangragoreiton, can be found
across two rows adorned with
bull heads and a lion relief.
This refers to the producers
of mandrake (Mandragora), a
root characterized by a sort of
anthropomorphic shape, which
historically was associated
with aphrodisiac and medicinal
properties.
To testify the variety of
spectacular activities taking
place in the arena, a significant
contribution may come from
the podium reliefs and their

clear iconography. In fact, a
distinct characteristic of this
stadium is the extensive use
of reliefs adorning the podium
walls of the arena. Although
the original plan likely called
for approximately 150 reliefs,
only twenty-six have been
found during the unearthed
operations across the twentyseven
cercises (wedgeshaped
seating sections).
The most significant reliefs
were dedicated to athletic
and equestrian depiction:
the reliefs portray various
activities, like horse and
chariot racing, alongside
depictions of awarded prizes
and some talamoni probably
used to gather some “good
luck” in superstitious gesture
from the participants to the
competitions. The reliefs
representing gladiatorial
contexts are undoubtedly
extremely fascinating, and
capture significant attention.
Recent excavations have
uncovered these reliefs
depicting single and couples
of gladiators. However,
distinct architectural evidence
suggests that the stadium
was not the place of Bloody,
deadly confrontations, so
these reliefs probably do not
represent lethal combats.
Unlike other structures in
the same area, dedicated to
gladiatorial matches, likes the
stadia at Perge or Aphrodisias,
Magnesia lacks the protective
barriers or high walls necessary
to shield spectators from
wild animals or desperate
combatants. Consequently,
it is hypothesized that these
reliefs deficit gladiatorial
training or exhibition matches
rather than fights to the death.
Nowadays, the principal group
of reliefs is usually protected
by a robust metal cage, used to
avoid damages from the visitors
or potential thieves or vandals.
DIGITAL SURVEY
To digitally document the
Stadium and its rich set of artistic
and cultural/social elements, it
was planned a three step session
based on photogrammetry,
in September 2024, a team
composed by G. Verdiani, A.
Camiz and U. Özdemir operated
a general coverage of the whole
architectural surface of the
stadium, operating about 1000
drone/UAV shots and about
5000 terrestrial shots, all these
data were processed in a single
photogrammetry producing a
well detailed general model of
the stadium, with an high level
of details and full texturing.
In September 2025, a unit
composed by G. Verdiani, E.C.
Giovannini, F. Tioli, A. Rosone,
C. Mastroberti and E. Miho
operated the photogrammetry
of all the reliefs of the podium,
getting them in a lucky moment,
with all the cages temporarily
removed. This produced about
4000 pictures from which It
was obtained a full set of very
high resolution models and
orthophotos of these particular
artworks.
The models derived from
this second session showed
interesting aspects, in fact, It is
possible to notice some original
features: the size of the stones in
the podium is constant in height
(about 82 centimetres) while the
widths may vary. This variation
sees the realization of the reliefs
on one main stone, but then,
they are easy at having parts
on the consequent block, even
for just minor details or small
parts of the figures. In this way
there is often the presence of
richly sculpted stones connected
to almost flat ones if not for
single details. This may allow
us to hypothesize the original
presence of painting completing
the scene and having the reliefs
emerging in colours and from
a flat scenario. Something
impossible to verify, while time
and nature have completely
cancelled any trace of paint
from the surfaces, but something
stimulating the speculation
about the original aspects of
the arena and worth of further
research. In the end, the third
session would be planned in the
future for completing the survey
of the writes and decorations
along the stands. The aim is
developing a 3D map of this
specific built heritage using the
main model of the stadium as a
reference for each detail making
possible and easily accessible a
multi-resolution model of this
fascinating building.

Abstract
The Stadium of Magnesia ad Maeander represents one of the most monumental and well-preserved athletic
architectures of Asia Minor, distinguished by its scale, architectural complexity, and rich cultural significance.
Built in the first century AD along the slopes of two hills, the stadium accommodated approximately 30,000
spectators, closely connected to the city’s civic life. Archaeological investigations have progressively revealed its
architectural layout, installations for athletic competitions, and extensive sculptural and epigraphic programs.
Originally associated with the Leucophryena festival dedicated to Artemis, the stadium hosted a wide range of
events. Architectural analysis, however, suggests that its design was optimized primarily for athletic and light
equestrian activities rather than full-scale chariot racing. Of particular importance are the reliefs decorating
the podium walls and the numerous inscriptions carved on seating and architectural elements, which provide valuable
insights into social stratification, professional associations, inter-city relations, and elite patronage within
Magnesia. Recent digital documentation campaigns employing UAV and terrestrial photogrammetry have enabled
the creation of high-resolution 3D models of the stadium and its sculptural elements. These digital datasets
support multi-scalar analysis, enhance interpretative possibilities, and contribute significantly to the long-term
study, conservation, and dissemination of this exceptional architectural complex.

CASE STUDIES
On Stage in Antiquity, On Screen in the Digital Age:
Two Thousand Years of urban presence and integration
of the Theatre in Priene
by Giorgio Verdiani, Andrea Rosone
The theatre of Priene,
among the best-preserved
in Asia Minor, represents
an exemplary case study
for testing integrated
methods of digital
surveying, procedural
modeling, and virtual
reality applied to
archaeology.
ANCIENT PRIENE AND
ITS THEATRE
Priene was founded in the Caria
region of the western part of
Anatolia, the present Turkey,
the settlement is situated on the
southern slope of Mount Mykale,
overlooking what in antiquity was
a gulf opening into the Aegean
Sea. From the Archaic period to
the Hellenistic age, however, the
silting of the Maeander river, once
entering the sea at the East of
Priene, had gradually pushed the
coastline westward, detaching
Priene from the seashore that
had once defined its economy
and strategic importance.
The city was architecturally
realised in the IV century BCE,
providing a model environment
for the implementation of a
rational, orthogonal urban plan,
organized in a series of large
terraces, the sloppy topography
imposed constraints that
required a specific architectural
attention, producing one of the

clearest surviving examples of
Hellenistic city planning. Priene
is a paradigmatic example of
urban planning of that time
(Wycherley,1945). Its street
grid, in which It Is possible to
recognize the Hippodamian
principles, organises the city
into regular sectors aligned to
the cardinal directions, though
subtly adapted to the mountain
slope. Public buildings at
Priene, including the Agora, the
Bouleuterion, the Prytaneion,
and the Theatre, participate
in a coherent architectural
vocabulary, presenting specific
solutions, but remaining coherent
to the city layout.
The Theatre of Priene is situated
on the third urban terrace of the
ancient city, in an intermediate
position between the agora and
the sanctuary of Athena Polias.
The building, exploits the terrain
and cliff slope and has most of
the additional parts and all the
external elements constructed
in marble blocks. It exhibits the
canonical articulation of Greek
theatres (Lawrence, Tomlinson,
1996): cavea, proedria, orchestra,
proskenion, stage building, and
parodoi. The cavea is organized
into five radial sectors, separated
by six stairways approximately
0.92–0.96 metres wide. The lower
rows are carved directly into the
rock, while the upper ones rest
on an artificial foundation made
of regular stone blocks; only part
of these upper rows survives
today, while many of the benches
have been lost. The seats consist
of superimposed slabs with an
average height between 39 and
40 centimetres, calibrated to the
natural slope of the hillside.
The curved layout of the benches,
reconstructible thanks to
historical surveys and comparison
with photogrammetry, shows
slight irregularities suggesting the
use of arcs with non-coincident
centers. This aspect, apparently
secondary, becomes relevant
in digital modeling because it
requires avoiding geometric
simplifications that are too rigid
and would misrepresent the
original construction logic.
Between the cavea and the
orchestra lies the proedria,
arranged as a paved band of
stone blocks that hosted the
row of honorary seats. In this
area, five marble thrones and a
central altar are still preserved,
elements likely added during
a later phase compared to the
original configuration. The
thrones feature articulated
bases, lion-paw legs, ivy motifs,
and curved backs with Ionicvolute
armrests; the quality of
the carving and attention to
detail confirm the representative
function of this zone, reserved
for civic and religious authorities.
The orchestra measures 18.65
m in diameter and corresponds
almost exactly to the length of the
proskenion. The latter represents
one of the distinguishing features
of the Theatre of Priene, as it
preserves twelve frontal pillars
and several lateral ones still
standing. The Doric entablature,
now fragmentary, originally
displayed rich polychromy:
triglyphs outlined in purple,
metopes alternating in black and
white, red cornices and fillets,
blue architraves. These painted
traces, documented by Wiegand
and Schrader, were adopted as
references for defining materials
in the digital reconstruction
(Wiegand, Schrader, 1895-1898).
From the proskenion façade,
stone beams project toward the
rear, connecting the scene front
to the back wall and supporting
the wooden floor of the upper
level. The stage rooms, now
completely lost, were accessible
through five doors whose
positions are reconstructible
thanks to historical drawings.
The stage building, particularly
its vertical development and its
relationship with the proskenion,
was reconstructed following the
hypothesis proposed by Armin
von Gerkan, which integrates
the Priene data with typological
comparisons to other theatres
(Gerkan, 1921). The parodoi,
located on the sides of the scene,
still preserve their masonry
access structures and constitute
an additional point of comparison
between the existing state and
the reconstruction.
Overall, the Theatre of Priene
stands out for the exceptional
amount of preserved lower
architectural elements and for
the quality of the historical
documentation available. This
dual condition makes it possible to
produce a digital reconstruction
that does not merely offer a
formal restitution but explicitly
clarifies the relationship between
what is preserved, what can be
reconstructed with reasonable
certainty, and what remains
hypothetical.
THE PHOTOGRAMMETRIC SURVEY
The definition of the current
state was carried out through
a photogrammetric survey that
combined ground-based and
drone-based imagery. A total of
824 images were acquired: 795
ground shots taken with a SONY
ILCE-6000 mirrorless camera
and, for the detailed recording of
the proedria, with a Nikon D800e
equipped with a macro lens; and
29 aerial images, produced using
a DJI Spark drone flying at low
altitude above the orchestra
and the cavea. The ground shots
followed a radial path along the
cavea and a linear path along
the proskenion, with multiple
fan-shaped captures to ensure
redundant coverage of shaded
areas.
Processing was performed in
RealityCapture. The initial
alignment of the images generated
several separate components due
to the presence of vegetation,
visual discontinuities, and scale
differences between aerial and
terrestrial shots. To bring the
model into a single reference
system, shared Control Points
were identified across the
various components, placed on
clearly recognizable elements
(slab edges, throne bases, joint
intersections). Introducing at
least three common points
made it possible to merge
all components into a single
macro-model.
DIGITAL MODELLING
The goal of the digital modeling
process was not to produce
a single static model, but

to construct an information
structure capable of explicitly
describing the geometric and
typological functioning of the
theatre. To this end, the work
was carried out in Rhinoceros 7
with the support of Grasshopper,
organizing the complexity of
the monument into a network
of objects, instances, and
metadata.
Deconstruction
and macro-structure
The theatre was divided into five
macro-groups: cavea, proedria,
orchestra, proskenion and stage
building, and parodoi. Each
group includes sets of recurring
elements: steps, benches, bases,
backs, thrones, columns, pillars,
beams, slabs. For each typology,
a single reference object was
modeled, conceived as a simple
geometric “prototype.” The
repetition of elements within
the theatre occurs exclusively
through instances, generated and
controlled parametrically.
This choice makes it possible
to drastically reduce the
computational weight of the
model, simplify updates, and
make the relationship between
typology and occurrence explicit.
Any modification to the reference
object automatically propagates
to all its instances, maintaining
the overall coherence of the
system.
Generative elements
Generative elements are
abstract geometries that define
the spatial arrangement of the
components. Linear elements
rely on points and vectors,
curved ones on oriented
curves, and complex joints on
reference planes or surfaces.
The curves were extracted from
the photogrammetric model by
projecting the outlines of the
cavea, the proedria, and the
proskenion onto plan view and
removing local irregularities.
These curves were parametrized
within the 0–1 interval, assigning
each parametric value a point
in space and a local reference
system (a triad of axes). On these
planes, the transformations
required to place the instances,
translation, rotation, and,
where necessary, slight scaling,
were calculated. This ensures
that the repetition of seats or
proskenion blocks follows the
real curvature of the theatre,
including small deviations from
an ideal geometry.
In areas where the original
blocks are no longer present,
particularly in the upper part of
the cavea, the arrangement was
reconstructed by interpolating
the available data: the average
distance between slabs, the
apparent radius of preserved
sectors, and the alignment
with the retaining walls. The
geometric assumptions adopted
were explicitly marked in
later stages through metadata
categorization (Rosone, Verdiani,
2024).
The resulting mesh was densified
and subsequently simplified,
maintaining high definition in
key areas (proedria, proskenion,
orchestra) and reducing detail in
peripheral zones. A set of highresolution
textures preserved
the chromatic and material
information necessary for the
reconstruction phase. Metric
verification was carried out
by comparing the model with
the measurements recorded
by Wiegand and Schrader:
the deviations observed fall
within an acceptable margin
for an indirect survey, making
the model suitable for the
subsequent phase of procedural
modeling.
Objects, instances,
and deformations
The objects were modeled in
Rhinoceros as low-complexity
meshes, sufficient to clearly
describe the basic form of each
element. The instances are
generated in Grasshopper, which
calculates for each one the full
set of transformations derived
from the generative elements.
This procedure produced
thousands of components with
complete control over their
positioning.
For curved elements or those
adapted to non-planar surfaces,
such as the backs of the proedria
or certain slabs of the cavea, the
process continued in Blender
using CurveDeform and similar
modifiers. In practice, the linear
object is “wrapped” along a
reference curve while maintaining
consistent proportions and detail.
Here as well, the deformation is
described within the metadata,
ensuring that the relationship
between object, curve, and
instance remains fully traceable.
XML metadata
The informational structure of
the model is defined through a
metadata system exported in
XML format (Erik T. Ray, 2001).
Each object and each instance
corresponds to a node within
the XML tree and is described
through:
4 the name of the typological
object;
4 the path to the reference
mesh file;
4 any associated generative
curve or surface;
4 position, rotation, and scale
coordinates;
4 the assigned morphological
variant;
4 the reliability category
(existing state, confirmed
reconstruction, hypothesis).
This structure allows the model
to be reloaded and regenerated
across different environments
without loss of information. The
XML file therefore does not simply
list objects: it describes the
procedural logic that determined
their spatial arrangement,
enabling the entire process to
be reconstructed directly from
the data.
Once the procedural model was
generated, it was imported back
into Rhinoceros and overlaid
onto the photogrammetric
mesh. Verification concerned
both geometric coherence
and the relationships between
parts (alignments, symmetries,
distances between key elements).
To express the degree of reliability
across different portions,
a chromatic classification
system was adopted: green for
elements matching the surveyed
existing state; yellow for parts
48 ArcheomaticA N°3 2025

reconstructed with strong
support from historical sources;
red for hypothetical elements,
especially in the upper portions
of the stage and the higher levels
of the proskenion.
This visual distinction, combined
with the categories stored
within the metadata, allows
anyone using the model to
immediately recognize the
nature of each element, avoiding
the misconception of a unified
reconstruction when in reality it
is based on very different levels
of certainty.
DIGITAL RENDERING
AND PHOTOREALISM
The transition from procedural
modeling to graphical rendering

took place in Blender, where the
model was imported together
with its XML metadata. The
goal was not merely to obtain
a convincing image, but to
construct a scene consistent
with the historical period
chosen for the reconstruction,
corresponding to the Doric
phase documented by Wiegand,
Schrader, and Gerkan, while
excluding later additions from
the advanced Hellenistic and
Roman periods.
Sculpting and
morphological variants
Although typological objects
had been modeled correctly,
they initially appeared too
“perfect” when compared to
the real appearance of stone
blocks. For this reason, each
object underwent a sculpting
process (Xury Greer, 2022), which
involved temporarily increasing
polygon density in order to add
micro-irregularities such as
chipped edges, abrasions, small
fractures, and depressions. The
work was carried out using a
graphics tablet, treating the
elements as proper digital
sculptures.
From each base object,
several variants were then
produced, differing in the
intensity of imperfections and
fracture patterns. During scene
generation, these variants were
assigned to instances through
a controlled randomization
system, avoiding visual repetition
and restoring the natural
heterogeneity of the materials.
Procedural materials
In parallel with geometric
work, material definition
was developed. Based on the
photographic dataset from the
survey, reference textures were
created and integrated with
procedural maps in Blender’s
Shader Editor. Normal, roughness,
and displacement maps were
combined to reproduce the grain
of the stone, surface absorption
variations, and ageing effects.
The procedural component,
managed also through Open
Shading Language (Larry Gritz,
2020), introduced microscopic
random variations in color and
roughness without requiring an
excessive number of distinct
textures. Here too, the link
between material and instance
is stored within the metadata,
enabling controlled regeneration
of the model in different
environments.
Environment and context
The theatre was placed within
a simplified environment
reproducing the current
landscape of the site, without
reconstructing the entire ancient
city to keep computational
costs and complexity under
control. The main slope,
selected vegetation masses,
and an HDRI-based lighting setup
were modeled and calibrated
to simulate neutral daylight.
This configuration allows for a
clear reading of the theatre’s
volumetry, cast shadows, and
the overall visual effect of the
scene reconstructed according to
Gerkan’s hypothesis.
VIRTUAL REALITY
The model, once prepared,
was exported into Unity for
the creation of an immersive
environment (J. G. Bond, 2017).
The goal was to offer a virtual
visit experience useful for
comparing the current state with
the proposed reconstruction.
Importing and
optimization in Unity
Within the game engine, several
panoramic camera positions
were created, corresponding
to significant viewpoints: the
orchestra, the proedria, the
lateral sectors of the cavea,
and the lowered viewpoint
at stage level. Each position
was transformed into a 360°
panorama, allowing the user to
explore the surroundings through
gyroscopic sensors or standard
joystick-based controls.
Interface and
interpretative functions
The navigation interface
features a simplified map of the
theatre, with buttons enabling
rapid selection of the desired
viewpoint.
The application was developed
for Android devices and desktop
computers, with the possibility
of use both through VR headsets
and in “flat-screen” mode.
This dual configuration makes
it suitable for exhibition and
museum contexts as well as
for educational and research
scenarios.
CONCLUSIONS
The work carried out on the
Theatre of Priene shows how
the integration of historical
sources, photogrammetric
survey, procedural modeling,
and virtual reality can generate
a digital model that is not merely
a three-dimensional replica, but
an actual tool of knowledge. The
centrality attributed to Armin
von Gerkan’s reconstruction
hypotheses for the scene, verified
50 ArcheomaticA N°3 2025
Cultural Heritage Technologies 51
and integrated in light of the
survey and the documentation
of Wiegand and Schrader,
demonstrates how digitalization
does not replace archaeological
judgment, but makes it more
readable, verifiable, and
communicable.
The decomposition of the
theatre into typological objects
and instances, described
through XML metadata, enabled
the construction of a scalable,
updatable, and interoperable
information model across
different software environments.
The rendering phase in Blender
transformed this abstract model
into a photorealistic scene able
to convey the material quality of
the marble, the imperfections
accumulated over time, and
the spatial articulation of the
complex. The implementation in
Unity finally made the theatre an
explorable environment.
In this sense, the Theatre of
Priene becomes a laboratory
for defining procedures that
can be transferred to other
contexts of archaeological
heritage: a method that starts
from historical documentation,
compares it with digital
surveying, builds a transparent
procedural model, and returns
it in accessible an d immersive
forms. The scene, which in
antiquity hosted theatrical
performance, became today a
space for the representation of
knowledge, no longer only a place
of spectacle, but an interface
between data, interpretations,
and contemporary audiences.
From a methodological point of
view, one of the most significant
outcomes is the possibility of
keeping three levels separate
yet in continuous dialogue: the
measured data, its geometric
abstraction, and its immersive
translation. The transition from
the survey to the VR scene
does not occur in leaps, but
through a chain of traceable
transformations, each of which
leaves a “signature” within
the metadata. This makes the
model not only reusable but
also open to critical revision: a
hypothesis can be replaced, a
parameter updated, an entire
section regenerated without
having to start again from
scratch. In a context where
technologies evolve rapidly, this
capacity for adaptation becomes
a fundamental requirement for
any digital archaeology project
that aims to endure over time.
Abstract
The Theatre of Priene is a well-preserved example of Greek theatrical architecture, offering an exceptional
case study for the integration of historical documentation and digital methodologies. The theatre dates to the
late Classical and early Hellenistic period and preserves cavea, orchestra, proedria, and proskenion. It was the
subject of extensive documentation during late 19th-century excavations, which provides a solid foundation
for interpretative reconstruction. This study presents a comprehensive digital workflow combining photogrammetric
survey, parametric modelling, and virtual reality visualisation. UAV and terrestrial photogrammetry
allowed producing a metrically reliable 3D model, subsequently refined through data cleaning and validation
against historical sources. The model was then transposed into typological elements governed by generative
rules, enabling the creation of a metadata-based system. The integration of detailed modelling and material
rendering further enhanced the legibility of architectural forms and surface characteristics. Finally, the digital
model was implemented within a virtual environment to support immersive exploration and comparative
analysis between the current state and reconstructed hypotheses, demonstrating how the convergence of archaeological
evidence, digital survey techniques, and advanced visualisation tools can produce a coherent and
accessible narrative for both scholarly investigation and public dissemination.

CASE STUDIES
The value of itinerant fragments
between Asia Minor and Europe
by Giorgio Verdiani, Pelin Arslan,
Elisabetta Caterina Giovannini
Built heritage embodies
accumulated layers
of human activity,
including construction,
transformation, abandonment,
reuse, destruction, and
rediscovery. Each monument or
archaeological site constitutes a
palimpsest whose interpretation
requires both technical rigor and
intellectual sensitivity. When
the life of a building brings it to
the present time, in the form of
archaeological remains, it may
appear as a fascinating ruin or
a poor mass of rubbles. In any
case it may offer an interesting
occasion of reconstruction
and a complex situation of
musealization or reuse. It may
bring in its ruins the presence
of invaluable artworks, statues,
mosaics, frescoes, past items
for everyday life, and even old
weapons.
These elements are well known
by archaeologists or other
professionals in the field of
cultural heritage, in practices
that often collect and may
take in a short trip these
findings to a restoration and
then to a local museum or to
some abroad destination. This
second condition was extremely
common during the past two
centuries. The collection and
exhibition in the museum of
findings from the smaller to
entire parts of architectures,
was a procedure seen as aimed
at the preservation of important
materials from difficult context
and was supported by the
early passage from a logic
of “collection” to the one of
“patrimony of humanity”. Thus,

parts or other archaeological
findings, may be resumed into
two main categories: the first
collects those items, like small
statues, tools, accessories and
artworks which are independent
from the architectural setup of a
place, which may have a minimal
impact on the aspect and
readability of an archaeological
site and/or its physical or
virtual reconstruction. The
second regards statues and
architectural parts that are
key elements in the reading
and interpreting the original
shape of the archaeological
building, which once removed
and placed in a museum cause
a lack in the possibility of
reading their balance between
the architectural dimension
and the displaced part. For
example, in the course of
the XIX and XX centuries,
archaeological exploration of
monumental sites in Asia Minor
led to the discovery of large
urban scenarios, recovering
significant sets of findings
and moving them to European
museums for restoration, study,
safe storage and exhibition.
About one century later, digital
technologies provide the means
to mitigate the spatial and
interpretive fragmentation
caused by historical removals.
Photogrammetry, modelling
from point-cloud dataset, and
3D visualization enable precise
comparisons between objects
preserved in museums and
those remaining in situ. These
techniques allow scholars to
virtually reunite dispersed
materials, reconstruct their
architectural relationships, and
reassess hypotheses regarding
their original placement or
function. Even more, the creation
of proper digital replicas,
potentially allow the physical

reconstruction of dispersed
items, their completion with
missing parts, interpolation by
abstraction, or using reference
models, and then allow the
production of real parts that may
be put back in place in the best
affordable conditions. In fact,
it is important to remember
that all the displaced items
have no chance in going back to
their original site, they may, at
the best, go back into another
museum, while an accurate
reproduction can go back on
site, in a digitally enhanced
anastylosis that put no threat
to the original piece.
Developing researches in
this field appears extremely
interesting, recomposing the
parts has also the additional
value of recreating a two ways
condition that is very valuable,
from one side it is possible to
bring back virtually or even
physically one or more missing
parts to their original location,
not as ruins, but as working
part of a reconstructed system;
from the other it is possible to
enrich the present location of
the item or parts with a virtual
environment that re-connect the
subject to its original location. A
sort of double site-specific setup
that can be considered one of
the most innovative progresses
in exhibition setup.
Taking as subject a small set
of statues and architectural
remains from Priene, in the
Hellenistic area of the actual
Turkey, whose excavation
and subsequent dispersal of
artefacts, particularly to Berlin,
appeared like an ideal test
research aimed at the digital
reunification of items and places
using digital solutions. The
occasion to start this experiment
of virtual recompositing of
the parts between Priene
and the European museum

was supported by the kind
availability from the Altes and
Pergamon Museum in Berlin, in
the specific, a special thank goes
to the director of both museums,
Martin Maischberger, who
hosted and gave full availability
welcoming and trusting a first
series of surveys in both museum
collections. In October 2022 and
in May 2024, two single days of
photogrammetric operations
allowed taking the data from
some significant items and
starting a study about how to
restore a link between places
and elements using digital
models. The Altes museum hosts
mostly statues, with only one,
the Priestess Nikeso, with a clear
and specific relationship with
the architectural space; all the
architectural parts are instead
preserved at the Pergamon
museum. In the case of the
statue of Priestess Nikeso, its
finding happened in 1898 in the

ruins next to the statue in-situ
plinth, in front of the main
entrance to the Sanctuary of
Demeter and Kore. The sculpture
consists of two main parts: the
statue, missing the head, and its
plinth, the overall height is of
about two metres. The statue
of the priestess is made of finegrained
yellowish-white marble,
while the plinth is made of grey
crystalline marble it may be
supposed to be a reused element,
on it there is a write in Greek
indicating “Nikeso, daughter of
Hipposthenes, wife of Eukritos,
priestess of Demeter and Kore”.
The figure is upright, with her
upper body and shoulders
slightly turned left. The other
statues digitalized at the Altes
Museum and coming from Priene
are: a Statuette of Dionysus
(height: 70.5 cm), a Statuette
of Aphrodite (height: 61.5 cm),
a Statuette of a Young Man
(height: 76.5 cm), a fragmented
statuette of Alexander the
Great (partial height: 31.6 cm).
All these statues present a high
artistical value, thus they can’t
be defined as key elements of
an architectural space. Instead,
the statue of Nikeso looks clearly
in a robust relationship with
the spatial organization of the
Demetra’s Temple, defining a
specific aspect of its entrance.
The architectural parts at the
Pergamon museum were a
partial reconstruction of an
altar, with a statue and a small
fragment of bass-relief coming
from the Sanctuary of Athena
Polias, ca. 200 BCE, a partial
reconstruction of the Sanctuary
of Athena Polias’ entablature,
and a partial reconstruction
of the temple entablature,
from the Temple of Asklepios,
the Agora, IVth–Ist centuries
BCE. For the entablature from
Athena Polias, it was possible
to have a parallel with another
part, this time hosted at the
Archaeological Museum in Mileto,
Turkey another part of the same
architecture, migrated not that
far, but another fragmentation
of the original building. The
full survey work in Berlin was
conducted by photogrammetry,
using specific cameras and
lenses to help achieve the
most complete and optimized
results and with the benefit
of using movable scaffolding
in the case of the Pergamon
Museum. The survey operation
in Priene was completed using
both photogrammetry and 3D
laser scanner survey, this second
option was extremely efficient
for the survey of the large
architectural remains in Priene
in 2022 during the workshop.
The photogrammetry was
instead used on architecture for
the Demetra’s temple, covered
by a combination of terrestrial
and drone/UAV shooting as side
activity during the workshop in
Magnesia in 2025. At the moment
of writing the development of
the research is still ongoing,
the first complete digital
recompositing will be probably
the virtual recoloration of the
Priestness Nikesa in the ruins
of the Demetra’s temple on the
Priene hill.
Abstract
Built heritage constitutes a layered record of human activity, often surviving as fragmented architecture and dispersed
artefacts. Historical excavation practices frequently removed architectural elements from their original
contexts, generating spatial and interpretive disconnections. This study explores the potential of digital technologies
to virtually reunite displaced heritage, focusing on selected statues and architectural fragments from the Hellenistic
city of Priene, now divided between the archaeological site and museums in Berlin. Through photogrammetry, laser
scanning, and 3D modelling, the research investigates original spatial relationships and proposes a dual framework in
which digital recomposition enhances both archaeological interpretation and museum presentation while preserving
the integrity of the original artefacts.

CASE STUDIES
Other Subjects, same approaches
By Andrea Pasquali, Ylenia Ricci,
Stéphane Giraudeau.
Contemporary architectural
practice often privileges
new construction, risking
the loss of architecture’s
socio-cultural dimension
in favour of standardized,
market-oriented production.
This paper argues for the
re-emergence of reuse as a
fundamental design strategy,
rooted in historical building
practices that emphasized
adaptation and material
continuity.
The contemporary evolution
of people’s identities
and the fragmentation
of cultures developed in
the modern age, supported by
current geopolitical ideologies,
define a highly urgent landscape.
Today’s conception of
architecture tends to consider
the boundary of the territory
as a rigid and defined category,
fixing languages, methods and
materials within coherent but
obligatory design models. We are
faced with a form of engineering
of design thinking that could
lead to the loss of the socio-cultural
component of architecture
in favour of a consumerist application
of the activity of building.
The danger is that architecture
will become more of a product
to be consumed than a cultural
act, transforming itself into
something standardised, fast,
productive and market oriented.
Although much of contemporary
practice concerns
existing heritage, the imagery of
today’s architecture continues
to emphasise new construction
as the prevailing model of innovation.
Technological progress
and the demand for low-impact
buildings have led to architectural
works being conceived as a
set of new components, created
or assembled at the same time
as the building itself.
This approach to design reached
its peak in the second half of the
XIX century and continues today
as the correct and canonical
method, defining architectural
design as the use of “the new”
as the only strategy for resolving
a project. Looking at the history
of architecture and construction,
particularly before the industrial
revolutions, and more markedly
in the former but subsequently
also in the civil/popular sphere
of the latter, the act of building
(adapting and reconstructing)
has always been associated
with strategies for reusing and
adapting architectural components
and building materials.
By its very nature, reuse, both
as a practice of stripping and
as recovery from rubble, is not
subject to a codifiable method
or a defined proportional measure,
and constitutes an essential
element of design identity. The
rhetoric of the new introduced
by industrial society and amplified
in the twentieth century
by the shift away from the rural
world has gradually marginalized
this dimension. However, in
contemporary times, reuse must
re-emerge as an integral part
of the act of building. A mindset
oriented towards reuse can
facilitate the search for design
solutions capable of minimising
the impact of new works on the
environment and, at the same
time, attributing a higher identity
and historical value to the
building. Looking back at history,
where the use of non-contemporary
architectural fragments in
new constructions is a recurring
practice, it is possible to recognise
in these grafts the strongest
elements of cultural continuity
and memory of the built
environment. Furthermore, the
presence of such elements helps
us to understand the evolution
of the property and adds to the
architectural object’s response
to living a method of archiving,
not only of the artefact but also
of the historical events that took
place during its construction.
The interpretation described
above has matured in our contemporary
age thanks to cultural
movements and dialogues that
emerged at the dawn of the

modern world. structuring the
interpretation of architecture
from a historical perspective.
It is easy to accept that the
design philosophy of the past
was not guided by this awareness
but rather by a functionalist
approach that led to the choice
of existing components because
they were more advantageous
both in economic terms and in
terms of optimising processing
times. This outlines a basic
structure more consistent with
the functionalist perspective of
post-industrial modernist thinking,
which finds accuracy in the
statement “architecture is an
image of its time because it is
the fruit of that time”. So, what
is the architecture of this time?
Can our contemporary world
still conceive of building as a
form of writing with characters
and methods generated entirely
from scratch, or, learning from
the past, evolve into a more reasoned
form that allows for reuse
and goes beyond the functionalism
for which it was created,
arriving at a more culturally
evolved and useful profile?. This
line of reasoning aims to open
up a possible interpretation of
the design structure without
providing a final summary. The
input of interest is to describe
cases addressed in past research
and work that define a useful
set of elements to justify the
reasoning profile. A case study
particularly relevant to this
theoretical framework is represented
by the Medusa protomes
preserved in the Basilica Cistern
in Istanbul. These are two stone
blocks carved with the head of
Gorgon, most likely belonging to
previous monumental contexts
and reused during the construction
of the great cistern
commissioned by Justinian in 535
AD (Önlü, 2010; Kaldellis, 2016).
Their current location, used as
bases for two columns, is an eloquent
example of the transition
from spolia in se to spolia in re
(Settis, 1984): the elements, created
with a specific symbolic and
apotropaic function, lose their
original meaning and take on an
entirely pragmatic and structural
role within the new architectural
structure.
Their reuse, devoid of iconographic
intent and determined
by considerations of material
availability and constructional
functionality, has nevertheless
produced a paradoxical effect: it
is precisely this practical reinterpretation
that has ensured the
preservation of the artefacts to
the present day. The protomes,
which survived because they
were transformed into simple
supporting elements, are therefore
an emblematic example of
how reuse can alter, suspend or
overwrite the original cultural
value while ensuring the material
survival of the object.
Survival that is perpetuated over
time thanks to recent technologies
for the digitisation of architectural
heritage, which allow
specific means and methodologies
to be used to collect data
(Guidi, 2013), produce material
and bring to light faded morphologies
of ancient ruins, giving
them new life in the digital age.
A new dimension of usability is
created for the asset, and the
reused fragment becomes a cognitive
artefact, capable of inhabiting
digital, virtual and immersive
scenarios, inaugurating a
third life in the present.
One of the further potentials
of digitisation lies in its ability
to restore context to fragments
that, for various reasons, have
found themselves without a
background capable of enhancing
them. A representative case
is that of the Tetrarchs of St.
Mark’s Square in Venice (Verdiani,
2019), a double group of
statues in Egyptian red porphyry
depicting four figures in high
relief, located at the corner of
St. Mark’s Treasury. During their
removal, one of the statues lost
a foot, but the fragment, now
preserved in Istanbul, is nevertheless
deprived of its original
context and displayed in a secondary
position. This creates
the risk of a lack of knowledge
and requires an interpretative
awareness about the artefact.
Digitisation can help to remedy
through virtual reconstruction
and a new narrative of its historical
and material value, promoting
its dissemination to the
masses (Verdiani et al., 2022).
In light of these considerations,
the issue of reuse takes on a dual
significance. On the one hand, it
constitutes a current and necessary
design approach, capable
of reducing the impact of new
works and restoring meaning
and identity to buildings. On
the other hand, it is precisely
the reuse adopted in past centuries
that has allowed the survival
of numerous architectural
elements which, reinserted into
subsequent structures, have survived
the passage of time to the
present day. It is thanks to this
material continuity, the result of
layered grafts and reuses, that
we now have a rich heritage,
ideal for digitisation, documentation
and accessibility through
contemporary digital survey
technologies.

CONCLUSIONS
The value of workshop
teaching and some reflections
by Giorgio Verdiani, Andrea Pasquali
Beyond the pleasure coming
from working in beautiful
places, operating on
extremely interesting architectures,
getting feedback from the
participants and seeing them
taking significant step forward
as professional and cultural operators,
the lessons learned from
fourteen different workshops and
from a large set of activities in
Archaeological areas, Built Heritage
and valuable Cultural Heritage
items in the past ten years,
is double. On one hand it comes
clear that a correct dataset,
proper documentation and following
archiving is always a valuable
resource for the management
of the Patrimony and allows the
real development of knowledge
and the connection between the
historical value and any following
event along the way. In any
possible future case, from new
research to possible transformations
of the surveyed subjects,
these archives are a witness that
goes far from the simple photos
and fix a robust point in the state
of knowledge about a place and
its architectures. Operating in
articulated scenarios, like it is for
the “recomposition” of itinerant
items moved from the place of
finding to far (and very far) museums
is a classic sample of how
the research may be widening a
field and pose solutions in line
with the Logic of “Patrimony of
the Humanity” which is a strong
concept that should be reasoned
keeping the distance from nationalistic
or just melancholic logics
of real or supposed belonging.
What comes out from this variety
of activities, May appear
fragmentary, isolated, a series of
sparse parts in episodic research.
But this can be more a point of
strength than a weakness. Indeed,
at now the structuring of rational
national and international digital
archives is on the way, pretty far
for being completed and efficient,
a number of tentatives in
years have taken their way, proposing
more or less innovative
approaches and interventions in
the creation of dedicated archives
that rarely remained alive after
the end of each financed projects.
But things are ongoing and this
progress is on two fronts: the
first correspond to the group of
large, structured archives, like
the Italian National Digitalization
Program (Progetto Nazionale di
Digitalizzazione - PND) and Internet
Culturale (Biblioteca Digitale
Italiana - BDI) or Portale Inventari
& Archivio Digitale (Sistema Archivistico
Nazionale - SAN) and Europeana,
which may considered the
most aged tentative of defining
an extended catalogue, at the
moment their real capacity in
offering access to digital survey
products is quite inconsistent,
but not out of the intentions. The
other front is one of the initiatives
from the school, academic,
research and enthusiast communities,
single or multiple tentatives,
at small or even medium size, that
aim at the production of specific
contents and are spontaneously
creating a vast and sparse archive
of contributions. They may look
dispersive, but in their multiplicity
they contribute to other research
and produce results and enhancements
to the knowledge in the
most various fields. In this series
of products the use of existing
platforms for sharing and presenting
contents is quite common,
with results that are sometimes
solid and durable, sometimes live
just the time of each project. In
this scenario, keeping durable,
efficient, archives of the materials
is not helped by the software
development, which tends more
in a stubborn innovation with poor
real benefits than in promoting
easy recovering procedures for
the older data. The logic of
“throwing away” old things seems
uncompliant with any Digital Heritage
intentions, but is constantly
applied in the software market.
For this, producing and storing the
original data “as acquired”, developing
them in the most various
software, but in the whole producing
basic, long term compliant
60 ArcheomaticA N°3 2025

formats, looks like the best way
to give a future chance to gather
data. Storing them online can be
a proper solution, thus a wearisome,
time consuming and quite
expensive physical backup (especially
on optical supports like DVD
and Blue-Ray discs) is still nowadays
an extra safeguard for important
contents. Some updates on
the data formats, along the years,
may contribute to an even more
complete and efficient long life of
the digital survey datasets.
This first point, obviously, does
not solve how this procedure
leaves an apparently incoherent
group of original and processed
data. The most effective reply to
this condition is probably leaving
them in this way and embracing
the logic of dissemination
“from the base”, taking time for
producing accurate and shareable
models and representations
exploiting existing platforms
that make these archives easy
to retrieve and find. A model
uploaded in sketchfab.com can
be found by a variety of people
searching for that specific item;
one or more graphic boards or
short reports produced from a
thesis or at the end of a research
may be uploaded and shared on
zenodo.org or figshare.com with
instant and efficient DOI (Digital
Object Identifier) attribution,
so to make their localization a
constant from that moment. A
short video, even without a professional
cut or montage, may
take part to the youtube.com or
vimeo.com platforms, allowing
the fast communication of some
results or leaving a trace of that
workshop or research activity.
The interlinking of these contents
to other scientific products may
expand and enhance the quality
of papers in conference proceedings
and journals, bringing them
a step forward in the digital heritage
scenario and extending the
options for clear and exhaustive
communication.
In conclusion, until the definition
of archiving protocols that take
into account the preservation of
usability and guarantee the maintenance
of future readability of
the data, both collected and processed,
the open dissemination of
all the components of the studies
and projects is to be considered
the most appropriate strategy for
improving the longevity and integrity
of the scientific documentation
of the Cultural Heritage.
