Derinkuyu Underground City

Derinkuyu Underground City lays in the Derinkuyu district in Nevsehir Province of Turkey. The city is a five layer underground complex of approximately 60 meters in depth that could possibly shelter 20,000 people along with their livestock and food supplies. The "city" could be closed from the inside by huge stone doors and each floor could be closed separately. On the second floor there's a room with a barrel vaulted ceiling which is believed to have been used for a religious purposes along with study rooms next to it, as well as a church at the bottom level. There's a 55 meter ventilation shaft that could also provide water to both the villagers above the structure and inside. It was also connected to other underground cities by miles of tunnels. It is thought to have been built by Phrygians in the 8th–7th centuries in the soft volcanic rock and may have been enlarged later in the Byzantine era. Many scholars believe that it may have been built by Persians due to references of refugee settlements by the Persian king Yima.

Open to tourists

In the year of 1969 around half of the underground city was opened to tourists.
