General view of Gobekli Tepe archaeological site in Sanliurfa, Turkey, on July 27, 2019. Gobekli Tepe is the oldest, biggest, and most mysterious archaeological site on the planet. Gobekli Tepe is the oldest megalithic structure ever found on earth. Discovered in modern-day Turkey, and still yet to be fully excavated, it dates to a baffling 12,000 years old. It's not just the oldest site; it's also the largest. Situated on a flat, barren plateau, the site is a spectacular 90,000 square meters. That's bigger than 12 football fields. It's 50 times larger than Stonehenge, and in the same breath, 6000 years older. The mysterious people who built Göbekli Tepe not only went to extraordinary lengths they did it with laser-like skill.

Göbekli Tepe means in English, Pot-Belly Hill. The tell has a height of 15 m (49 ft) and is about 300 m (980 ft) in diameter. It is approximately 760 m (2,490 ft) above sea level.

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 weighs up to 10 tons. They are fitted into sockets that were hewn out of the 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 details of the structure's functi
