About northeast of the city is the famous Neolithic site of Göbekli Tepe, the world's oldest-known temple, which was founded in the 10th millennium BCE. The area was part of a network of the first human settlements where the agricultural revolution took place. Because of its association with Jewish, Christian, and Islamic history, and a legend according to which it was the hometown of Abraham, Urfa is nicknamed as the "City of Prophets."
