Located in Sanliurfa province Sauth East of Turkey.  Gobeklitepe was added to UNESCO World Heritage List in 2018

Gobeklitepe (Turkish for the ‘hill of the navel’) is a 1000 foot diameter mound located at the highest point of a mountain ridge, around 9 miles northeast of the town of Şanlıurfa (Urfa) in southeastern Turkey. Since 1994 CE, excavations conducted by Klaus Schmidt of the Istanbul branch of the German Archaeological Institute, with the cooperation of the Şanlıurfa Museum, have been taking place at the site.

Gobeklitepe consists of four arrangements of monolithic pillars linked together by segments of coarsely built dry stone walls to form a series of circular or oval structures. There are two large pillars in the centre of each complex which are encircled by slightly smaller stones facing inward. Archaeologists believe that these pillars could have once supported roofs. The structures vary in size between around 33 and 98 feet in diameter and have floors made of terrazzo (burnt lime)
