Top 10 Unexplained Mysterious Structures On The Earth
6. Gobekli Tepe, Turkey
Gobekli Tepe is an archaeological site at the top of a mountain ridge in the Southeastern Anatolia Region of modern-day Turkey, approximately 12 km (7 mi) northeast of the city of Şanlıurfa. The tell has a height of 15 m (49 ft) and is about 300 m (984 ft) in diameter. It is approximately 760 m above sea level. It was excavated by a German archaeological team under the direction of Klaus Schmidt from 1996 until his death in 2014.
The tell includes two phases of ritual use dating back to the 10th – 8th millennium BCE. During the first phase, pre-pottery Neolithic A (PPNA), circles of massive T-shaped stone pillars were erected. More than 200 pillars in about 20 circles are currently known through geophysical surveys. Each pillar has a height of up to 6 m (20 ft) and a weight of up to 20 tons. They are fitted into sockets that were hewn out of the bedrock. In the second phase, 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 PPNB-period. Younger structures date to classical times.
The purpose of the structures is not yet clear. Excavator Klaus Schmidt believed that they had been early neolithic sanctuaries.
