1963, a man in Turkey noticed his chickens were disappearing through a small crack in his basement.

He knocked down the wall to find them, but instead he found a dark tunnel.

Eighteen stories underground, he had stumbled upon a massive hidden city that had been sleeping right under his feet for centuries.

This is Derinkuyu, a subterranean marvel carved into solid volcanic rock.

At 85 meters deep, it could house 20,000 people for months without them ever seeing the sun.

Ventilation shafts, water wells, churches, stables, and kitchens designed to disperse smoke without alerting anyone outside.

To stay safe, they used massive circular stone doors weighing half a ton that could only be opened from the inside.

Early Christians hiding from Roman persecution.

Byzantine Christians hiding from Arab raids.

When invaders arrived, entire villages simply vanish into the earth.

They sealed the doors and waited in total silence.

Raiders would walk through empty streets, find nothing and leave, never knowing a whole civilization was breathing right beneath their boots.

Archaeologists discovered it was linked by a five kilometer tunnel to another city called Kaimakli.

In fact, over 200 of these underground cities have been found in the region.

A massive interconnected world that was forgotten by history until one man's chickens went missing.

If you lived back then, would you have the courage to disappear underground to stay alive?
