Derinkuyu Underground Cityvisitor guide.

In the Derinkuyu district of Niğde, an eight-level underground city carved into Cappadocia’s volcanic tuff extends deep below the surface. Engineered with self-sufficient living spaces capable of sheltering thousands of inhabitants, Derinkuyu represents one of the region's most extraordinary archaeological monuments, with roots extending from early Phrygian and Assyrian eras through Roman and Byzantine use.
