Скачать или смотреть The Secret Underground City of Derinkuyu

Deep beneath Turkey lies Derinkuyu — an ancient underground city carved thousands of years ago, stretching 18 levels down and large enough to shelter 20,000 people.

But the biggest mystery remains: who built it, and what were they hiding from?
