The four concentric stone circles of Yellowmead Down are situated about half a mile to the south east of Sheepstor village, between Yellowmead Down and Ditsworthy Warren. There is a barely visible burial cairn in the centre surrounded by four rings of stones set within one another. The circles are quite small; the outer being 66 feet in diameter and the tallest stone 4ft 3 inches high. On the west side of the circles there is a small double stone row leading downhill away from what appears to be possible remnants of a fifth circle or outer arc on this side. Slightly uphill to the north-east, there appears to be the remains of a much smaller cairn circle. The site was discovered by Richard Hanson Worth in 1921 and restored by the Reverend Hugh Breton on behalf of the Dartmoor Preservation Society in that year. In 2008 Bournemouth University carried out a further investigation under the Dartmoor National Park Authority's Monument Management Scheme. They discovered that the restoration work had been accurate and also found a flint scraper which has been dated to the Neolithic/Early Bronze Age periods.
