One of the more interesting and less well-understood sites that we visited was a Byzantine church complex that appears to have been a renovation to an earlier, polytheistic temple. As I understand it, the bases of the four piers in the church are uncharacteristic of the Byzantine cave churches.

The upper part of the complex has eroded and collapsed, leaving much of it exposed. There are still several adjoining cave-rooms, but the exposed portion makes for a beautiful photosynth.
