Archaeologists from Sheffield and other universities have discovered a lost stone circle a mile from Stonehenge, on the west bank of the River Avon.

The stones were removed thousands of years ago but the sizes of the holes in which they stood indicate that this was a circle of bluestones, brought from the Preseli mountains of Wales, 150 miles away. Excavations in August–September 2009 by the Stonehenge Riverside Project uncovered nine stone holes, part of a circle of probably 25 standing stones. (Most of the circle remains unexcavated, preserved for future research, whilst the 2009 excavation has been filled back in.)
