Summary

Cropmarks on an aerial photograph have revealed the NW quadrant of the defences of a fort on a spur of a broad undulating terrace on the NE side of the valley of the River Nith. The overall configuration of the defences, and indeed the extent of the interior, are unclear, but three ditches are visible on the photograph, the outer two lying concentrically to each other on an arc that appears to cut across the axis of the spur at its neck, and the innermost converging on their line westwards before cutting back sharply towards the SSE and returning across the spine of the spur after a distance of some 60m. While the course of the outer ditches is lost in the pasture field to the NE, and masked by natural markings along the SW and S flanks of the spur, it is likely that these belong to a fortification that essentially blocks the easiest line of approach from the NW, though none of the slopes elsewhere are particularly steep, while the innermost ditch may belong to a settlement inserted into its interior. If this interpretation is correct, the projected extent of the underlying fort may be in the order of 0.35ha; probably rectilinear on plan, the settlement is set obliquely across the axis of the spur. No entrances are visible and the interior is featureless.
