Summary

This fort is situated on a low hillock formed between two gullies and has been defended a belt of ramparts and ditches drawn in a shallow arc across the N approach and along the NE flank. On the N the defences are 20m deep and comprise three ramparts with intermediate ditches, but where the slope steepens along the NE flank the two outer ramparts peter out, though the middle rampart reappears at the E end. The innermost is reduced to little more than a scarp, which can also be traced along the SW flank of the promontory, but excavations about 1900 by David Christison (1901) found two, stone-packed, palisade trenches to its rear on the N side of the interior; varying between 3,5m and 5.5m apart they were not strictly concentric and may represent separate phases of occupation. The roughly oval interior of the fort, which is otherwise featureless, probably measures about 95m from ESE to WNW by 45m transversely (0.35ha). The entrance probably lies along the W margin of the promontory on the NW
