The National Technical University of Athens undertook the compilation of an "Integrated Diagnostic Research Project and Strategic Planning for Materials, Interventions Conservation and Rehabilitation of the Holy Aedicule of the Church of the Holy Sepulchre in Jerusalem". This paper focuses on the work merging the geometric documentation with the characterization of materials, the identification of building phases and the diagnosis of decay and pathology through the use of analytical and non-destructive techniques. Through this integrated approach, i.e. through the documentation and characterization of the building materials, through the diagnosis of decay and pathology, through the accurate geometric documentation of the building and through the non-destructive prospection of its internal structure, it was feasible to identify the construction phases of the Holy Aedicule, identifying the remnants of the preserved earlier constructions and the original monolithic Tomb. This work, thus, demonstrates that the adoption of an interdisciplinary approach for integrated documentation is a powerful tool for a better understanding of monuments, both in terms of its structural integrity, as well as in terms of its state of preservation, both prerequisites for effective rehabilitation.

Keywords: Ground penetrating radar (GPR), 3D modelling, Holy Aedicule An interdisciplinary team from the National Technical University of Athens is performing the restoration of the Holy Aedicule, which covers the Tomb of Christ within the Church of the Holy Sepulchre in Jerusalem. The first important task was to geometrically document the monument for the production of the necessary base material on which the structural and material prospection studies would be based. One task of this action was to assess the structural behavior of this edifice in order to support subsequent works. It was imperative that the internal composition of the construction be documented as reliably as possible. To this end several data acquisition techniques were employed, among them ground penetrating radar. Interpretation of these measurements revealed the position of the rock, remnants of the initial cave of the burial of Christ. This paper reports on the methodology employed to construct the 3D model of the rock and introduce it into the 3D model of the whole building, thus enhancing the information about the structure. The conversion of the radargrams to horizontal sections of the rock is explained and the construction of the 3D model and its insertion into the 3D model of the Holy Aedicule is described.

Cultural routes are a well-established development tool to highlight and promote a region’s cultural and environmental reserve, as well as having a positive impact on a region’s socio-economic development. Underdeveloped or rural areas, which have limited financial and technological resources available, often envision cultural routes as a useful development tool to cater to their needs. However, unless these cultural routes are designed and implemented based on the principles of a circular economy or while respecting the region’s cultural identity and heritage, their impact will not be significant. The region of Aitoloakarnania is the poorest prefecture of Greece. The prefecture served as a case study to demonstrate that the utilization of its cultural and architectural heritage can be based on the identification, documentation, and the reveal of paths of cultural tourism along the region’s main natural features, namely its rivers, lakes, lagoons, and coastline. Τhe density and the representative distribution of the monuments in the area, in combination with the unique natural environment of the prefecture, led to the configuration of a mild design of cultural routes, promoting the revealing of both the cultural and the natural landmarks of Aitoloakarnania. In this framework, certain cultural paths were defined. The first one, along the Acheloos River, includes sites of natural heritage, ancient and medieval monuments (castles, fortifications, monasteries, churches, burial sites, archaeological sites, etc.). The other cultural path regards sites along the Evinos River and Trichonida Lake, which includes similar monuments and traditional settlements. A similar cultural path regards cultural sites and points of interest along the coastal parts of the prefecture, and in particular, a path initiating from the historic city of Nafpaktos and following the route to the west, it reaches the Venetian castle of Plagia, opposite of Lefkada. These cultural paths fuse along their routes sites of natural heritage, sites of archaeological and cultural interest, and sites of historic importance to the region. This amalgamation of different types of cultural sites, integrated into a single cultural entity, provide the means for the local and regional development in a sustainable approach while ensuring and disseminating the region’s brand and history.
