Imagine that you are going to do a work at home, you tear down a wall in the basement and a stone cabin appears. And a corridor. And another cabin. And you go down some stairs, and others, and others. And it turns out that you’ve just discovered an underground city that’s over 3,000 years old.

This happened in 1963 to an inhabitant of Derinkuyu (Turkey), discovering an underground city that could house thousands of people in its day.

The Derinkuyu Underground City has up to 18 levels below ground, and the first level is estimated to have been excavated around 1,400 BC. It is, according to the investigations that have been carried out, a fortress to protect the inhabitants of the city of the surface in case of enemy invasion, equipped with all kinds of traps to defeat the invader.

Inside, heavy stone doors have been found to prevent access from the outside, long corridors that connect the different rooms, water wells, warehouses for food, vents, stables, schools and even a temple; But let’s stop imagining and see it in this short video by Luis Tobajas:
