Located 14 km northeast of Avanos, this underground city was built on the northern slopes of Mt. Idis, in an area with strata made up of volcanic granite. The extensive galleries of the city are spread out over a large area and connected to each other by tunnels. The underground cities in Kaymakli and Derinkuyu, are very narrow (5 cm) and there are long holes between the different levels of the city that were used to provide communication between the different levels of the city. The ventilation of these neatly carved out rooms was provided by these holes when the city was sealed up against enemies.
The city was discovered in 1972 by the local muezzin and farmer Latif Acar, when he was trying to find out where the water disappeared, which was supposed to run towards his crops.
Similar to Kaymakli and Derinkuyu, Ozkonak has a ventilation system, a water well, a winery and rolling stone doors.
Opening hours : Summer 08.00 – 19.00; winter 08.00 – 17.00
