Cappadocia, a region in central Turkey, is known for its Göreme National Park, a UNESCO World Heritage Site. The area is famous for its "fairy chimney" rock formations, some of which reach 40 metres (131 ft) in height. From the 4th to 13th century CE, occupants of the area dug tunnels into the exposed rock face to build residences, stores, and churches.Photo credit: Mila Zinkova
