Kilise Camii cave church in the Valley of Erdemli
The valley of Erdemli contains a Byzantine settlement from the 9th to 13th century. The main complex is the Saray Manastırı (palace monastery) with a decorated facade, a big cave church and several spaces on the bottom of the valley. The hillsides contain hundreds of caves with several cave churches and a cave mosque. This cave church with frescoes from the 13th(?) century is just underneath the small cave mosque.
