"Chapel of the Angel"
The current chapel of the Angel, the area before the Holy Grotto that serves as its antechamber, had been part of the holy site ever since the pre-Byzantine building. The mosaic with the Greek inscription citing the Deacon Conon of Jerusalem and the stairway carved in the rock to connect the upper level with the mosaic floors to the lower level of the Chapel of the Angel are testimony to this.
The chapel that now no longer has walls is marked out by four granite columns standing on a balustrade. These divide the presbytery from the chapel. The columns belonged to the Sanctuary of the Crusader period and supported the chapel vaults.
