Dulkadirli Underground City The Dulkadirli Underground City, which was constructed by Christians during the 4th and 5th centuries and later utilized by Byzantium, Seljuks, and Ottoman, is located 50 km south of Kirsehir. The entrance to the underground city is reached through a 22-meter tunnel, leading to a 30x50 meter interior courtyard embellished with columns extending out of the stone walls. On the east, west, and north sides of the courtyard, there are five living rooms and eight other rooms, all freely accessible from the outside through sixteen round arches. The only way to reach the lower level is by a ladder from the fifth room, which also contains a water well. Within the gallery, two stone masses are present that were originally believed to be millstones, but were more likely used as door-closers. At the end of the gallery, a small millstone has been discovered, and some speculate that early Christians inscribed the surface with various messages. A two-courted settlement lies 130 meters east of the underground city, characterized by its unique architectural features and presentation plan conditions, differing from other Seljuk inns.
