The twin valleys of Soganli are scattered with pyramid-shaped rock pinnacles that were first hollowed out in the Roman era.
By the time the Byzantine period was in full bloom, Soganli had become a major monastic center, its rock pinnacles home to chapels and monk cells.
The Karabas Kilise (Black Hat Church), Yilanli Kilise (Snake Church), and Sakli Kilise (Hidden Church) have the best preserved frescoes in this chapel cluster.
