This is something else! A previously unknown metropolis has been unearthed in Turkey. It was discovered during an urban development project started by Turkey’s Housing Development Administration in the Nevsehir province of Central Anatolia. The metropolis is a 7 kilometer span of tunnels, chambers, and escape galleries.
The upper levels of the complex were first seen in 2013, but the full size of the metropolis wouldn’t be discovered until 2014. About $35 million was invested into this project, but after the discovery, construction was halted and the area was registered with Turkey’s Cultural National Heritage Preservation Board, making sure this piece of history is protected forever.
“It is not a known underground city. Tunnel passages of seven kilometers are being discussed. We stopped the construction we were planning to do on these areas when an underground city was discovered,” said TOKİ Head Mehmet Ergün Turan.
Not much has been revealed about the underground tunnels. It does consist of various rooms, tunnels, hidden churches, and contains numerous artifacts that date back as far as 5,000 years. It may also be the world’s largest underground city.
