A team of archaeologists has discovered a major new prehistoric monument close to Stonehenge.
Fieldwork and analysis have revealed evidence of 20 or more massive prehistoric shafts — more than 10 metres in diameter and five metres deep — forming a circle more than two kilometres in diameter around the Durrington Walls henge.
Researchers believe the features are Neolithic and were excavated more than 4,500 years ago, around the time Durrington Walls was built, and that the shafts served as a boundary to a sacred area or precinct associated with the henge.
Experts from the University of St Andrews were joined by counterparts from Birmingham, Warwick, the University of Wales Trinity Saint David and the Scottish Universities Environmental Research Centre.
