Saratli Kirkgoz Underground City Saratli Kirkgoz Underground City is a magnificent historical wonder that has captured the imagination of people with its rich history. Situated near the Aksaray-Nevsehir main road, about 25 km from the city center, it is considered to be one of the hidden gems of Aksaray. This underground city has seven floors, but only the top three are open for visitors. It consists of 40 units that were utilized as residences, toilets and storage rooms by the ancient Greek inhabitants. Saratli Kirkgoz Underground City, like other underground cities in Cappadocia, served as a refuge for early Christians fleeing from the brutal punishments of the Romans. This city had a self-sufficient environment that allowed the residents to stay inside for months without the need to go outside. To ensure the well-being and security of its inhabitants, the city had its own bakery, water well, and advanced ventilation system that provided fresh air to its residents. Apart from its function as a place of shelter and defence, researchers have discovered many tunnels that connect the peasants' homes to the underground city. The entryway doors are 1.5 meters tall, weigh about 200 kg, and have a millstone shape. These doors were designed to be used for shooting arrows through the holes in the middle of the doors during enemy attacks, as well as for communicating messages from inside the city about any issues.
