Ozkonak Underground City Özkonak Underground City, situated just 12 kilometers from Avanos in the province of Nevşehir, stands as a remarkable testament to the advanced architectural and engineering expertise of ancient times. The underground city was uncovered in 1972 when a local farmer observed that the water he irrigated his fields with was mysteriously vanishing into the earth. Özkonak ranks among the three major subterranean fortresses in the region, alongside Kaymaklı and Derinkuyu. This city consists of several levels carved from volcanic granite, interconnected by tunnels and equipped with a distinctive communication system, setting it apart from the Kaymaklı and Derinkuyu underground cities. Each chamber is fitted with its own ventilation shaft, indicated by the presence of pipes on every floor, which ensured air circulation even when the entrances were sealed during attacks. Like other local underground settlements, Özkonak features a water well, an efficient ventilation system, wine presses, and rolling stone doors. It is also home to the largest stone door in Cappadocia, measuring nearly 2 meters in height. Large holes in the floor near the exit are believed to have been used for food storage.
