This house, carved out volcanic stone, sits on the street in the old part of town in Avanos, Turkey. The carved wooden front porch was no doubt built at the same time as the house itself, more than 75 years ago. The central Anatolian Cappadocian region of Turkey is covered by rich, soft volcanic rock deposited by the eruption of Mt. Erciyes centuries or millenia ago. The area is now full of houses like this one built from the malleable stone, as well as caves used as houses and even underground cities and villages.
