Çatalhöyük is located overlooking the Konya Plain, southeast of the present-day city of Konya (ancient Iconium) in Turkey, approximately 140 km (87 mi) from the twin-coned volcano of Mount Hasan. The eastern settlement forms a mound which would have risen about 20 m (66 ft) above the plain at the time of the latest Neolithic occupation. There is also a smaller settlement mound to the west and a Byzantine settlement a few hundred meters to the east. The prehistoric mound settlements were abandoned before the Bronze Age. A channel of the Çarşamba River once flowed between the two mounds, and the settlement was built on alluvial clay which may have been favorable for early agriculture.
