In Turkey's Cappadocia region, a huge underground city has been uncovered beneath modern streets near Nevşehir Castle. This underground settlement spreads across several kilometres and may be even larger than Derinkuyu, the best-known underground city in the area. Discovered in 2013 during a housing development, archaeologists found rooms, tunnels, kitchens, chapels, and storage spaces carved deep into soft volcanic rock known as tuff. Cappadocia is famous for its underground cities, with at least 36 documented. These cities were built over centuries as safe places for people to live and protect themselves from frequent invasions. They had advanced designs including air shafts, heavy stone doors, and water wells. Sometimes, livestock were kept inside for warmth and food. The newly found city beneath Nevşehir covers almost five million square feet and reaches depths of over 110 metres. Artefacts show it was in use from Byzantine times through the Ottoman period. Researchers used seismic imaging to map the tunnels without digging, as the fragile rock demands careful work. Life underground was tough but organized. The community had kitchens, wineries, oil presses for lamp fuel, chapels for worship, and storage rooms. Despite the dark and crowded conditions, these cities were carefully planned and expanded over time. Cappadocia’s early Christian identity made it a target over centuries, but the underground cities helped its people survive in safety. Today, local authorities plan to open parts of this new site to tourists and build museums. Archaeologists continue slow excavations, ensuring safety while revealing the remarkable story of people who once lived beneath the earth as a normal way of life.
