The volcano erupted millions of years ago and formed a variety of rocks after natural wind erosion. The region's unique karst landform, which resembles the surface of the moon, is called "the most lunar-like place on Earth" and is also the scene of "Star Wars". In addition, since the 4th century, Christians have come to live here for refuge, building houses and cave churches. In 1985, Cappadochia was included in the United Nations Natural and Cultural Heritage List.
