Using powerful ground-penetrating radar, investigators working around Stonehenge have detected a trove of previously unknown burial mounds, chapels, shrines, pits — and most remarkable of all — a massive megalithic monument made up of more than 50 giant stones buried along a 1,082-foot-long c-shaped enclosure.This news is unreal — and it's resetting virtually everything we thought we knew about Stonehenge. Just a week after finding out that Stonehenge was once a complete circle, archaeologists from Birmingham and Bradford universities, and from the Ludwig Boltzman Institute in Vienna, have shattered the image of Stonehenge as a desolate and lonely place
After four years of painstaking effort, and by using a magnetometer, a ground-penetrating radar (GPR), and a 3D laser scanner, archaeologists have shown that Stonehenge was once a sprawling complex that extended for miles.
And then there's the previously unknown "super henge," a monument located just two miles from Stonehenge. Scans suggest that each buried stone is about three meters (10 feet) long and 1.5 meters (5 feet) wide. The stones are positioned horizontally, not vertically, but it's conceivable that they originally stood upright like other standing stones. The archaeologists suspect they were brought to the site shortly before 2,500 BC.
