Ihlara Valley

The Ihlara Valley (or Peristrema Valley; Turkish Ihlara Vadisi) is a canyon which is 15 km long and up to 150 m deep in the southwest of the Turkish region of Cappadocia, in the municipality of Güzelyurt, Aksaray Province. The valley contains around 50 rock-hewn Christian churches and numerous rock-cut buildings.

The earlier Greek name, Peristrema (Περιστρημα; winding round) of the village of Belisarma which is located about halfway along the valley from Ihlara to Selime, gave its name to the valley as well.

The canyon was formed in prehistoric times by the Melendiz River. It lies between the villages of Ihlara in the southeast and Selime in the northwest. At the north end of the village of Ihlara, there is a stairway with almost 400 steps, which descends over 100 m down into the canyon. From the 7th century AD, the valley was settled by Byzantine monks who dug their houses and churches out of the tuff stone, which had been deposited by the eruptions of Mount Hasan.

The Christian churches in the valley fall into two groups. The first consists of the churches near the village of Ihlara, which are decorated with paintings...
