Nine Stones, Winterbourne Abbas [SEP] Description and design
The Nine Stones circle has been described by Gale as "probably the most well documented of all those surviving in the county". It measures 9.1 metres by 7.9 metres (29 feet 10 inches by 25 feet 11 inches) in diameter, as measured from a north-to-south direction. The stones are of sarsen or conglomerate. A gap between two stones on the side of the circle adjacent to the road may suggest that there was once a tenth stone in the monument. Given its dimensions, the circle could only accommodate a small number of individuals assembling within it. Seven of the nine surviving stones are under 90 centimetres (3 feet) tall, but two of the northwestern stones are considerably larger.
