Derinkuyu: The Underground City Rediscovered Behind a Wall

In 1963, a chance discovery in Derinkuyu, Türkiye, brought one of Cappadocia’s most extraordinary underground networks back to public attention. Carved into volcanic rock, Derinkuyu contains narrow tunnels, hidden entrances, storage chambers, wells, ventilation shafts and enormous circular stone doors designed for defence. But who created it? Was it really 18 levels deep? Could 20,000 people shelter inside? And did a nine-kilometre tunnel connect it to Kaymaklı? This documentary separates documented history from popular legend and explores Derinkuyu’s rediscovery, Byzantine expansion and remarkable underground engineering.
