GPR Used to Locate Possible ‘Superhenge’ Near Stonehenge

Ground penetrating radar (GPR) antenna mounted on a small tractor surveying near the Stonehenge monument as part of a larger project that identified a row of 90 previously undiscovered stones less than 3 km from Stonehenge.

Archaeologists using high-resolution ground penetrating radar (GPR) have located a massive collection of stones less than 3 km from the well-known Stonehenge site. This grouping of 90 stones, up to 4.5 meters tall (14.7 feet) have apparently been pushed over and buried. Renderings of the site have been created showing what the row of stones would have looked like. The exact purpose and how this site relates to Stonehenge is still a mystery.
