Göbekli Tepe "potbellied hill", (partial excavation)

Anatolic Culture , (pre-pottery hunter-gatherers), founded 10th millennium B.C.E.; Abandoned, 8th millennium BCE, (Schmidt 2010) located Southeastern Anatolia Region of Turkey; this is a very mysterious, possibly astronomical, site still under intense study. The site was intentionally burried without destruction. Many of the T-shaped pillars are decorated with abstract, enigmatic pictograms and carved animal and humanoid figures in low and high relief, including lions, bulls, boars, foxes, gazelles, donkeys, snakes and other reptiles, arthropods such as insects, scorpions, arachnids, and birds, particularly vultures.

Elevation is 760 meters (2,490 feet) above sea level

Material: Monolithic 'T-shaped" stones columns, walls of small mortaless stones, roof unknown. Current archaeological thinking is that the T-pilllars supported wooden roofs in which the the entrances to the structures were placed.
