(FOXNEWS) — British researchers said Monday that they had discovered evidence of a larger version of Stonehenge located approximately 2 miles from the famous prehistoric site.
The site at Durrington Walls, located about 90 miles southwest of London, has been dubbed a "superhenge" containing as many as 90 large stones.

The researchers from the University of Bradford said they believed the monument was built about 4,500 years ago, according to Sky News. The stones were located using ground-penetrating radar on Salisbury Plain. They were found lying on their sides and buried under three feet of earth.
Some of the stones stood nearly 15 feet high and were originally placed along the south-eastern edge of a circular enclosure facing the Avon River that measured nearly a mile wide - making it the largest earthwork of its kind in Britain.
