Archaeologists find vast monument next to Stonehenge that dwarfs famous site

Archaeologists said they had found the buried remains of a mysterious prehistoric monument close to Britain’s famous Stonehenge heritage site.
Up to 90 standing stones, some originally measuring 4.5 metres and dating back some 4,500 years, may have been buried for millennia under a bank of earth, they said on Monday.
The discovery was made at Durrington Walls - a so-called “superhenge” located less than three kilometres from Stonehenge - thanks to hi-tech sensors, they said.
The site may have been used in neolithic times for rituals or as some kind of arena.

“Durrington Walls is an immense monument and up until this point we thought it was merely a large bank and ditched enclosure, but underneath that massive monument is another monument,” Vincent Gaffney, of the University of Bradford, told the BBC.
