Kaymakli Underground City is located in the village of Kaymakli in Cappadocia, approximately south of Nevsehir. It is one of the largest and best-known underground complexes in the region, associated with the historical landscape of Cappadocia, which is included on the UNESCO World Heritage List together with Goreme National Park and the rock sites of the surrounding area.

The complex was carved into soft volcanic tuff and expanded over a long period of time. It was most significant during the Byzantine era, when the underground shelters were used by local residents during raids and military threats. A well-planned system of rooms made it possible not only to hide, but also to sustain everyday life for long periods.

Several underground levels are known at Kaymakli, connected by corridors, stairways, and vertical shafts. Ventilation channels, utility rooms, storage areas, spaces for keeping animals, living quarters, and religious spaces have been preserved here. Massive round stone doors were used to protect the inner passageways, and the layout of the complex shows how carefully life underground was organized.

For tourists, Kaymakli is interesting because it offers the opportunity to see one of the most characteristic forms of Cappadocia's historical architecture not from the outside, but from within. A visit makes it easier to understand how the region's inhabitants adapted to the conditions of their time and used the properties of the local rock to create a complex and functional refuge.
