Listed since 1959, Cappadocia alone contains more than 200 underground cities. Of these, Derinkuyu and Kaymakli are among the few open to the general public. Unsurprisingly, they attract large numbers of curious visitors every year to discover this astonishing way of life. Other towns in the region are also well worth a visit, including the must-see Göreme, Uçhisar and Ürgüp.
Set out on several levels, the different rooms in these cities are built around ventilation shafts to let oxygen into the basements, to prevent death by asphyxiation. In fact, the deeper you go into the long underground mazes, the smaller the spaces become and the more scarce the fresh air... A strange experience, to be had at least once in your life. For safety reasons, but also to preserve places that are unique in the world, the lowest levels of these underground cities are generally closed to the public.
