The island Kythnos of Cyclades is of particular archaeological interest. The position has been inhabited

since the 12th c B.C. until the 7th c. AD, while remains of habitation already in the 3rd millennium B.C.

have recently come to light. From both inland and sea surface excavations numerous artefacts are

recovered covering a wide range of materials (various stones including marble, metals (gold, silver, copper,

iron and lead), ceramics, faience, glass, bones, ivory, in addition with numerous ancient buildings

(churches, altars, public buildings, plumbing installations, houses, harbor installations, funerary

monuments, etc.) and architectural members (columns, floors, mortars, plumbing columns, columns, etc.).

The uniqueness of the position is firstly due to the fact that systematic field investigations are carried out

with combinational methods (surface research, land and sea excavations) and with modern means and

documentation, with the participation of numerous scholars of different disciplines, and on the other hand

that an extremely rare total of artifacts (about 1500) of a wide range of materials, was recovered- since the

"sanctuary" of the temple in which all these items were placed was never bridged and all the artifacts were

found in situ. These findings seem to originate from many areas not only of the Aegean but also of the

Mediterranean in general, underlining the importance and the radiance of this sanctuary.

Archaeological finds show that since the dawn of historical times in Kythnos, man and stone are

connected. However, The cultural route of the stone and the loads of artefactst from various materials

(marble, glasses, bones-of people and animals-, roofs, etc.), from the extraction of the raw materials, to the

workshops, and to the final recipient, the resident of Kythnos, is largely unknown. Furthermore, we know

little about the population itself, about the palaeoclimatic changes that determined its life and caused the

timeless disintegration of the stone, but also about the effects of climate change on the monuments of the

cultural heritage.

Therefore, the scope of the project is the preservation / conservation and protection of cultural heritage,

with the timely and valid prevention of the deterioration of the monuments (mobile and immovable) in

relation to the diachronic archaic-micro-climatic parameters, the timeless reconstruction of the past through

the study of the archaeological finds and of human remains and the virtual tour in space and time, which

will implement the results from laboratory analyzes. The proposed actions have as a common link the

development of a smart advanced digital 3D Chrono-Geospatial Platform that will include:

• Development of an innovative non-destructive portable device, using an original method of surface

Lamb

waves for erosion testing of surfaces (lath or mortar), to determine the depth of the surface corrosion and

any stratification, and to calculate the depth of each layer.

• Developing an innovative Corrosion Tool, with a network of sensors and bio-contamination

networks, to

produce models that will realistically simulate the erosion of archaeological structures in the future,

• Development of bio-dome device,• Full three-dimensional mapping of the archaeological site and selected artworks by season,

Innovative archaeometric method (new integrated Isotopic Geology and Isotopic Anthropology) combined

with archaeological information, structured in a geospatial database• and timeless virtual tour throu space and time (Web apps, storytelling, AR).
