Uçhisar in Cappadocia
View at the faszinating tuff rock cones, where people lived until the early 1980s. The tuff stone makes it easy to dig caves into the soft rock. Living inside was much more comfortable than in a normal house. In summer the caves stayed cool and in winter dry and warm. The stability of the tuff allowed to create caves with several floors and there are even so called underground cities. They were used in times of danger to hide and had a sophisticated system for ventilation.
