Ozkonak is located 14 kilometres from Avanos and was discovered in 1972 by a local farmer. This farmer, Latif Acar discovered the underground city when he notices water going missing. The complex is made up of 10 floors, at a depth of 40 metres and it is thought it could house up to 60,000 people. Only four floors are open to the public now. The larger areas of the city are connected by tunnels, however, Ozkonak also had a system of pipes connecting each level, to allow communication in times of hiding. There are also holes above the tunnels used for dumping hot oil on the enemies.
