Derinkuyu Underground City:
85 meters below the ground with a complete city structure, Derinkuyu underground city is located in Nevsehir province. This underground city contains many sophisticated structures such as ventilation, church, stable and cellar, but only one-tenth of the city is accessible.
Some of the wells in the site have no connection with the ground level in case of poisoning during an invasion. So visitors who want to get a taste of a dramatically different life under the ground will be attracted by this place.
