 This is a symbolic copy of the Chapel of Holy Sepulchre in Jerusalem.Built between the end of the 13th and the beginning the 14th centuries, it was erected here to mark Svetitskhoveli as the second most sacred place in the world (after the church of Jerusalem), thanks to Christ's robe.In front of this stone chapel, the most westerly structure aligned with the columns between the aisle and the nave marks Sidonia's grave.
