Kaymakli is one of the 36 underground cities listed in Turkey to this day. However, it isn't possible to visit all of them because most of them have been buried and are no longer accessible. These cities were built so that the Christians could hide from invaders.
Kaymakli is located 12 miles from Nevsehir. Only four levels are accessible to the public although there are eight in total, descending approximately 20m. Air can circulate underground thanks to large ventilation shafts that run as deep as 70 to 80m. The doors are marked by huge stone discs that only open from the inside. A countless number of rooms then succeed one another: kitchens, wine cellars and stables for animals. The various spaces are connected by tunnels which you have to crouch down to get through.
