UNDERGROUND CITY OF DERINKUYU

85 m deep, one can see the rooms of an entire city recreated underground in order to entrench oneself in case of threats: barn, canteen, food and drink stores, wells, churches, ventilation tunnel... It is the deepest and the largest known underground city. It could accommodate 10,000 people. The rooms are wide and the corridors easy to access. The most astonishing thing is to learn that the visible part would constitute only one tenth of its real size.
