Archeologist Ergül Kodaş said his team was excavating the site as part of a project focusing on documenting and rescuing cultural sites located in the Dargeçit district, when they came across the 11,800-year-old sewer system and over two dozen architectural artifacts.
A total of 15 restorers and archaeologists as well as 50 workers are currently excavating the area, which was designated a historical and cultural site by Turkish authorities.
Kodaş, the head of the excavation team, said the historical site was inhabited for a long period around 9800 B.C. and that there were eight-story historical buildings reaching up to seven meters in height.
