Göbekli Tepe is an early Neolithic site in Urfa, southeastern Turkey. It is famous for containing the world's oldest known stone temples (dated to before 9000 BC), and because it contradicts the long-held belief that the introduction of agriculture preceded the construction of large buildings. Göbekli Tepe was created by hunter-gatherers, yet is assumed to be a key location for understanding the origins of agriculture. (To give a timescale, remember that Stonehenge, a Neolithic and Bronze Age megalithic monument located near Amesbury in the English county of Wiltshire, about 8 miles north of Salisbury, was erected between 2500 BC and 2000 BC although the surrounding circular earth bank and ditch, which constitute the earliest phase of the monument, have been dated to about 3100 BC.)
