A. Thom S3/1 Class II Survey
Construction: 1 circle and 2 ellipses both based on a 5, 12, 13 triangle. Circle diameter 372.4 ft = 336.8 my. Perimeter 429.8 my = 173.9 mr. Diameter drawn 136 my. The NE ring seems to be an ellipse. Major axis 39, minor axis 36. Perimeter 117.8 my = 47.1 mr. Note how the large stone at the east end of the minor axis has broken into four parts. The south ring also seems to be an ellipse. Major axis 52 my minor axis 48 my. Perimeter 157.1 my = 62.9 mr. Note that the major axes of the two ellipses are co-linear.

These three rings stand by the river Chew at 50 m O.D., 6 miles S of are oolitic limestone, possibly from Dundry Hill 4 miles NW. The rings lie on a bent NNE-SSW axis. The NE ring, once of 8 stones, measures about 106 x 98 ft (32.3 x 29.8 m); the Centre, about 372 ft 5 ins (113.5 m), and once had 28-30 stones; and the SW ring, 141 x 131. ft (42.9 39.9 m) with about 12 stones. All the stones are very large. The SW ring is badly ruined.
500 m NE the stump of an outlying stone, Hautville's Quoit, lies by the hedge of a field on a ridge overlooking the circles. 320 metres WSW of the Centre ring are 3 limestone slabs of a ruined Cove, now hidden from the circles by the village church.
Ruins of avenues extend from both the NE and Centre circles. The affinities with Avebury 30 miles to the east.
