Derinkuyu: The Underground City That Could Hide 20,000 People

In 1963, a man in central Turkey knocked through a basement wall and found a tunnel. Behind it lay Derinkuyu, a vast underground city carved into volcanic rock. Who dug it? Nobody can say for certain. In this video we go down through the city: the stables, kitchens and wine presses, the ventilation shafts and wells, the huge round stone doors that sealed from the inside, and the church deep below. We also look at the rival theories about who built it (Phrygians, Hittites, early Christians), what the sources say about its neighbor Kaymaklı, and which famous claims, like the long tunnel between the two cities, we could not verify. 📍 Derinkuyu, Nevşehir Province, Cappadocia, Türkiye Chapters: 0:00 The hook 0:31 The Discovery 1:51 The Descent 2:50 Life Below 4:03 The Air Below 4:43 The Stone Doors 6:01 The City Next Door 7:21 Who Built It? 9:13 Why Hide? 10:17 The Last Residents 10:52 Numbers and Doubts 12:17 What We Still Don't Know Subscribe to Shadow Archive for more history's hidden places, and see you in the next one.
