Another UNESCO World Heritage Site, the Cappadocia region in central Turkey contains unusual rock formations that were turned into dwellings. There were even vast, multiple-storied, underground cities extending for miles under the surface, supporting perhaps 35,000 - 50,0000 people. Early Christians defended themselves from persecution and even built churches in them. Today, in some of the towns, the hollowed-out rocks are incorporated into homes and other buildings, and in the countryside, farmers use them for storage. Tractors here were mostly Turkish Fiats.

Nearby volcanoes covered the area with ash and molten rock and the "fairy chimneys" and other formations are visible because these different deposits erode at different rates. Immediately we were put in mind of Badlands National Park in South Dakota.
