Summary

This earthwork, which encloses a low hillock in low-lying ground, is traversed from NNW to SSE by the road from Biggar to Hartree. Nothing is visible of the perimeter on the E side of the road, though RCAHMS investigators identified its course on vertical aerial photographs, while to the W twin ramparts with a medial ditch some 8m in breadth can be traced round the flanks of the hillock. Oblique aerial photographs, however, show the ditch turning back quite sharply adjacent to the road on the N, as indeed it was depicted by David Christison about 1889 (316-17, fig 16), suggesting that rather than being the circular enclosure some 76m in internal diameter postulated by the RCAHMS (1978, 145, no.272, fig 87), it is in fact oval, its E side approximating roughly to the line of the road. If this is correct, the interior measures about 80m from N to S by 55m transversely (0.4ha). The interior is featureless and the position of the entrance is unknown.
