150-200 Known Undergruond Settlements in Cappadocia
Some of the most interesting cultural riches in Cappadocia are the 150-200 known underground settlements of varying sizes. However, since there are cliff settlements of different sizes, in all the towns and villages in the region covering an area of 25 000 kmē., this number maybe underestimated. Most of the rock settlements of this kind were built by hollowing out the tufa from the ground. Except the traces made by tools while hollowing, we do not have much information about the techniques they used.
