How Did They Breathe 55 Meters Underground?

Beneath Cappadocia lies Derinkuyu — an extraordinary underground city carved into solid rock. Its rooms, corridors, stone doors, wells, and ventilation shafts formed an interconnected system that allowed people to shelter below while still receiving fresh air from the surface. In this video, we explore how natural ventilation, temperature differences, wind, vertical shafts, and underground passages helped move air through Derinkuyu — and why the smallest openings could be just as important as its enormous chambers.
