Unearthing Derinkuyu, The Hidden City Beneath Cappadocia

Derinkuyu, an ancient underground city in Capadocia, was rediscovered in 1963 when a man renovating his home found a hidden room. This led to the excavation of a vast network of tunnels, believed to have been built around 1000 AD during the Byzantine era to protect against wars and natural disasters. The city, 280 feet deep, could house 20,000 people along with livestock and supplies, making it the largest underground city in the region. It featured kitchens, stables, churches, wells, and schools, and may have connected to other subterranean safe havens.
