Mucur Underground City The Mucur Underground City is an extensive network of tunnels carved beneath the surface, estimated to be 7-8 meters (23 ft) deep and extending near Kırşehir Hakan Paşa Tomb. It originated during the Roman era, when Christianity was rapidly spreading in the 2nd century AD. At the time, there was a conflict between pagans and Christians over places of worship, and underground cities were created to offer refuge and safe environments for Christian worship. The Mucur Underground City is a spacious complex with numerous rooms, hallways, and corridors that have been excavated and cleaned over time. The tunnels include passages that serve as doorways, which one can only traverse by bending down. In 2015, a comparative study was conducted on the landscaping of the Mucur Underground City, which included surveying and measuring its dimensions. The results indicated that the passageways were mostly human-sized, while the reception rooms could accommodate small animals. Additionally, there were ventilation chimneys above ground.
