Ortahisar means “middle castle,” and as its name implies, it is central among the Cappadocian towns of Göreme, Urgüp, Uchisar and Nevsehir, and only a few kilometers from the Göreme Open Air Museum. When entering the town, you will notice doors in the rock surfaces on both sides. These doors are the best example of the cool-air storages in Cappadocia. In these natural air-conditioned rooms, lemons and oranges from the Mediterranean region, apples from Nigde, local potatoes, quinces and onions are stored. Green lemons slowly turn yellow in these store-rooms.
