Derinkuyu Underground City
Eighteen-level subterranean city in Cappadocia, descending 85 metres. Sheltered up to 20,000 people during Arab–Byzantine raids.
The Cappadocian landscape is famous for its pale rock cones and tall eroded cliffs. At Derinkuyu, the most unusual architecture is below the ground. Rooms, passages, storage spaces, stables, wells, and places of worship were cut into soft volcanic rock, forming an underground settlement that could be closed from the surface.
Derinkuyu is part of a network of subterranean towns in Cappadocia. UNESCO places these underground cities within a traditional human landscape that also includes rock-hewn churches, dwellings, and villages. They belonged to communities that lived, farmed, worshipped, and sought shelter in the same volcanic terrain.
Carving a town into the rock
Cappadocia's tuff is soft enough to cut with hand tools, yet strong enough to hold chambers when the spaces are planned carefully. People opened rooms beside one another, left supporting pillars, cut shafts for air and light, and connected levels with narrow stairways. The work created a settlement by removing material rather than stacking it.
The underground spaces could be used for food storage, wine making, animal shelter, craft work, and temporary residence. Large stone doors could be rolled across passages, turning the narrow routes into defensible points. The design was practical. A surface entrance could be closed while people and supplies remained below.
Ventilation was essential. Shafts carried air through the levels, while wells and channels helped provide water. The deeper rooms were cooler than the surface, which helped preserve food and made them useful even when there was no immediate threat. An underground city had to work on ordinary days before it could serve as a refuge on dangerous ones.
Refuge in a changing region
The history of the underground cities is complicated. Some spaces may have earlier phases, while much of the network was used and expanded by Christian communities in later centuries. UNESCO describes the Cappadocian landscape as a human habitat with roots reaching back to the fourth century, when monastic communities began living in cells cut into the rock.
In later periods, people gathered in troglodyte villages and underground towns to resist raids, including Arab invasions. Derinkuyu was one of several places where families could move below the surface with animals, food, and tools. The refuge was temporary, but the rooms had to be maintained long before anyone needed to use them.
That history makes the word “city” useful but imperfect. Derinkuyu was a connected set of spaces shaped by household needs, storage, worship, and defence, rather than a buried version of a surface capital with streets and public squares on the same scale. Its most important feature was the ability to disappear from view.
Derinkuyu and Kaymakli
[Kaymakli](/sites/kaymakli/) is another major underground city in Cappadocia. The two sites have different depths, room plans, and passageways. Local geology and the needs of each community shaped the layout.
Above ground, Cappadocia contains more than underground rooms. Rock-hewn churches preserve Byzantine paintings, while dwellings and villages show how people used the cliffs as part of daily life. Derinkuyu belongs to a much later period than the earliest settlements of Anatolia, and its design reflects the needs of communities living in Cappadocia's volcanic landscape.
A fragile monument below ground
The underground rooms are protected from some weather but vulnerable to other pressures. Moisture, unstable rock, changing ventilation, and heavy visitor traffic can damage surfaces that were never meant to carry modern crowds. Conservation has to manage the air and the stone as carefully as the original builders did.
Derinkuyu is memorable because the architecture works by subtraction. The walls, rooms, and passages were made by taking the mountain away, one cut at a time. The finished spaces record people planning for ordinary storage, crowded refuge, and the possibility that the safest place in the landscape might be the one no one could see.
