Summary

The remains of a possibly unfinished fortification enclose a rocky knoll at the E end of a ridge above Bonar Bridge. The main feature visible is an arc of quarry pits flanking a continuous internal bank, which spans the easiest line of approach along the ridge from the WNW, but a scarp can also be traced along the NNE flank and round the ESE end of the knoll, albeit that it has been heavily distorted and defaced by surface quarrying. No trace of it can be seen amongst the rock outcrops along the SSW flank, but the interior probably measures about 88m from ESE to WNW by 30m transversely (0.2ha). A gap in the bank at the WNW end is probably an entrance. Apart from quarries, the only features visible within the interior are two rectangular footings.
