The shrine of St. Thekla was located outside of Seleukeia in Isauria/Cilicia. Egeria, on her pilgrimage in 384, noted several monasteries and the church of the saint, all surrounded with walls for protection against the Isaurians, whose attacks in the early 5th century caused the church treasure to be removed to Seleukeia for safekeeping. The site contains two major churches: a richly decorated basilica built over the cave where St. Thekla allegedly descended into the earth, dated to around 375 with redecoration in the 6th century and a rectangular church with a central tower and an atrium with a large exedra. This latter church, similar in plan to Alahan Monastery and others of the region, was apparently dedicated by Emperor Zeno. The site also contains a necropolis basilica, a bath, and remains of fortifications. Its history after the 6th century is unknown.
