Cappadocia is recognized for its unique, subterranean cities which could be built only due to its geological features. In order to understand how these cities were built, you must take a trip into the past. In 1963, James Mellaart has discovered here the oldest fresco ever known. This is a 8000 or 9000 years-old mural being 2.5 meters wide and depicting an erupting volcano located on the top of what seem to be boxes.
Although this may seem bizarre, the mural actually represents the Hasan Da?? volcano, which is on top of the place where the fresco was found. What seem to be boxes is actually the Çatal Höyük city. Çatal Höyük is older than the Pyramids and was the home of 10000 people.
The largest city in Cappadocia, Derinkuyu was discovered in 1965 while one man was trying to clean its house and the wall broke. Behind the wall was an unknown room which led into another and another and so on. The city had at least 18 floors underground and could settle at least 30000 people. Moreover, the city is not yet totally explored. In the Derinkuyu, there is a wide tunnel which connects it with another subterranean city, this proving the fact that at a certain given time, Cappadocia was an entire hidden network of subterranean tunnels.
Now, the city is open to visitors and if you can’t go there and visit it, you can always see it online.
