Göbekli Tepe
Göbekli Tepe (, "Potbelly Hill"; known as "Girê Mirazan" or "Xirabreşkê" in Kurdish) is a Neolithic archaeological site near the city of Şanlıurfa in Southeastern Anatolia, Turkey. It includes two phases of use, believed to be of a social or ritual nature by site discoverer and excavator Klaus Schmidt. 
Its oldest layer dates to around 9000 BCE, the end of the Pre-Pottery Neolithic A (PPNA). The younger phase, radiocarbon dated to between 8300 and 7400 BCE, belongs to the Pre-Pottery Neolithic B. During the early phase, circles of massive T-shaped stone pillars were erected, classified as the world's oldest known megaliths, contemporary with other nearby settlements such as Nevalı Çori and Çayönü. In 2018, the site was designated a UNESCO World Heritage Site.

The tell or artificial mound has a height of and is about in diameter, approximately above sea level. More than 200 pillars in about 20 circles are known (as of May 2020) through geophysical surveys. Each pillar has a height of up to and weighs up to 10 tons. They are fitted into sockets that were hewn out of the local bedrock. In the second phase, belonging to the Pre-Pottery Neolithic B (PPNB), the erected pillars are smaller and stood in rectangular rooms with floors of polished lime. The site was abandoned after the Pre-Pottery Neolithic B (PPNB). Younger structures date to classical times. 

The excavations have been ongoing since 1996 by the German Archaeological Institute, but large parts still remain unexcavated.
