Cappadocia is famous for its weird and wonderful natural rock formations and unique historical heritage. One of the best places to see these strange formations is the town of Göreme, which is located among a large number of tuff cones, termed fairy chimneys. The fairy chimneys have been formed as the result of wind and water erosion of two different volcanic layers: A thick layer of tuff (consolidated volcanic ash) covered by a thin layer of basalt that is more resistant to erosion. Due to the ease of carving into the tuff, many of the fairy chimneys at Cappadocia have been hollowed out over the centuries to create houses, churches and storage facilities.
