This Man Found A SECRET Tunnel In His House. And It Led To A MASSIVE Underground City!
You may have heard stories about people renovating their homes, only to stumble upon a secret room. Perhaps it’s a play room? A cellar? A place to stash sensitive documents and treasures? All that mystery can be pretty scary yet exciting. But back in 1963, a resident of Nevşehir Province of Turkey found a secret room behind one of his walls. Which led to his discovery of the Ancient city of Derinkyu.

The city was used as a bunker during times of water or natural disaster.
