Deep beneath the surface of Cappadocia lies a network of ancient cities. Derinkuyu is the deepest of them all, reaching nearly 85 meters below ground.

These cities were built by early Christians to hide from religious persecution and invasions. They feature complex ventilation systems, schools, churches, and even stables for livestock.
