Kaymakli, one the largest and most important underground cities in Cappadocia, has all the accommodation needed for a community to live underground. The multipurpose rooms and halls are connected to one another by narrow corridors. Turkey's Cappadocia region is famous for its subterranean safe cities carved from soft tuff. These underground cities, which are among the most interesting cultural richness of Cappadocia, take tourists from all over the world on a mysterious journey every year. The underground cities in Cappadocia, interconnected by corridors, were used as hiding places by Christians in the 7th century. These subterranean cities were self-sufficient cities with granaries, stables, rooms, kitchens and ventilation systems. The most famous underground cities uncovered until now around Cappadocia are found in Derinkuyu, Kaymakli, Tatlarin, Ozkonak, Mazi and Ozluce. Derinkuyu Underground City and Kaymakli Underground City were inscribed on the UNESCO World Heritage List in 1985.
