A circle of deep shafts has been discovered near the world heritage site of Stonehenge, to the astonishment of archaeologists, who have described it as the largest prehistoric structure ever found in Britain.
Four thousand five hundred years ago, the Neolithic peoples who constructed Stonehenge, a masterpiece of engineering, also dug a series of shafts aligned to form a circle spanning 1.2 miles (2km) in diameter. The structure appears to have been a boundary guiding people to a sacred area because Durrington Walls, one of Britain’s largest henge monuments, is located precisely at its centre. The site is 1.9 miles north-east of Stonehenge on Salisbury Plain, near Amesbury, Wiltshire.
Prof Vincent Gaffney, a leading archaeologist on the project, said: “This is an unprecedented find of major significance within the UK. Key researchers on Stonehenge and its landscape have been taken aback by the scale of the structure and the fact that it hadn’t been discovered until now so close to Stonehenge.”
