The "City of Caves" refers to a network of ancient cave dwellings located in the region of Cappadocia, Turkey. These caves were carved into soft volcanic rock by early inhabitants, providing shelter and protection from invaders. The unique geological formations in the area allowed for the creation of extensive underground cities, complete with living spaces, churches, and storage areas. Today, the City of Caves is a popular tourist destination, attracting visitors interested in history and archaeology. Many of the caves are part of the Göreme National Park, a UNESCO World Heritage Site, showcasing the remarkable human adaptation to the natural landscape.
