Gani Tarkan, director of the Mardin Museum, who heads the excavations, said that while similar underground cities have been uncovered in Anatolia, the city in Midyat is completely different, The Daily Sabah added.
"Midyat has been used uninterruptedly for 1,900 years. It was first built as a hiding place or escape area," he said. "As it is known, Christianity was not an official religion in the second century.
"Families and groups who accepted Christianity generally took shelter in underground cities to escape the persecution of Rome or formed an underground city," Tarkan added. "Possibly, the underground city of Midyat was one of the living spaces built for this purpose. It is an area where we estimate that at least 60-70,000 people lived underground."
