Ground penetrating radar prospection of the construction phases of the Holy Aedicula of the Holy Sepulchre in correlation with architectural analysis

The Holy Aedicula of the Holy Sepulchre in Jerusalem was surveyed by ground penetrating radar in correlation with an architectural analysis, following a methodology suited for built cultural heritage assets. The construction layers of the building were revealed. Remnants of the original monolithic Aedicula were identified and comprise of two rock blocks surrounded by a masonry dating mainly to the 1810 construction phase. Results indicate that parts of the 11th century structure may have been retained in the 1810 reconstruction, such as the lower part of the masonry of the north side of the Chapel of the Angel. The south rock block appears to be fractured and the influence of two pillars that support the dome of the burial chamber and which are based on the rock block is assessed.
