These are the remains of the church of the Anemurium necropolis, dating back to the 5th century AD.
Anemurium was an ancient city in the former Roman province of Isauria. It marks the southernmost point of Asia Minor, only 64 km from Cyprus.
Anemurium already existed in the Hellenistic period. In 260 AD it was captured by the Sassanians, which sent Anemurium into decline for many decades, but it continued to be prosperous until the mid-7th century, when it was more or less completely abandoned, probably because the Arab occupation of Cyprus made the coast unsafe.
It is actually not situated in the Central Anatolia Region, but just south of it, in the Mediterranean Region of Turkey.
