Ortahisar, which means middle fortress in Turkish, Ortahisar has best example of cool-air storages in Cappadocia. In these natural air-contitioned 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.

The natural fortress in Ortahisar gives the name to the town. With its 90 metres height the castle is a prominant landmark in the region, honeycombed with caves and tunnels, camouflaged by nature without the slightest indication of human presence inside, has partly crumbled away, revealing some of its interior. Today it has been restored and the peak is accessible by staircase.
