In the east of Cappadocia lies Kayseri, the city known as Caesarea in Roman times. As with many human settlements in Anatolia, Kayseri has a long history and a rich cultural heritage. Located 20km from the city centre, the Kültepe Mound is the most important example of this heritage with a history dating back 6000 years. Kültepe was an important trading centre during the 2nd millennium BC. Excavations have unearthed important artefacts from the Bronze Age, the Assyrian trading colonies and from the Hittite era. One of the most visited sites in Kayseri is the Soğanlı Village of Yeşilhisar County. The village is an important centre of Cappadocia and there are about fifty rock cut churches in its environs.
