Normally when you knock down a wall you don’t expect to find much more than wires and pipes. But imagine knocking out a wall in your basement and finding a whole underground city!
In 1963 a man in Cappadocia Turkey decided to re-model his house. When he went to knock down a wall in his basement he found one of many hidden entrances to the underground city of Derinkuyu.
Derinkuyu was an entire city carved into the stone below Cappadocia. It is over 60 meters down and has 18 levels. It includes many “buildings” such as residencies, churches, schools, wineries, and food storage. It features vents to the surface and several discrete entrances. It was designed to house 20,000 people and some livestock.
It is believed that it was created to house people to shelter them from times of war. The churches were placed at the lowest level to protect them during times of religious persecution.
I seems to have been build during the 7th and 8th centuries BCE. There are several tunnels that run for miles and connect to other underground cities.
After the man rediscovered this lost underground city it was open to public tourists in 1969.
