The underground city of Derinkuyu in Cappadocia, Turkey, was rediscovered in 1963 during a basement renovation. Less than half of the city has been excavated, with many sections remaining sealed due to structural instability. The site extends to approximately 85 meters deep and could house up to 20,000 people. A Greek Orthodox church (Church of the Sacred Apostles) exists in Derinkuyu, dating to the 10th-11th century. 🏛️⛪
