"Inside the incredible underground city that once housed 20,000 people"

Ind:

Believed to have been created during the Byzantine era in 780-1180 AD, the city of Derinkuyu was likely used as a bunker to protect inhabitants during wartime or from natural disasters.

The city’s security system was complex with stone doors able to close from the inside to block intruders from entering, with each storey being closed off individually.

While only roughly half of the secret city is accessible, it is connected to other underground communities by tunnels that can stretch for miles.
