The monument comprises a fort which occupies a rocky promontory. The S and W sides are protected by sheer cliffs, but from the NE the approach is up a gentle grass-covered slope.
The fort is defended by a single wall which encloses an area measuring 54m by a maximum of 25m. On the NE, where there is least natural protection, the wall is up to 6m thick and the outer facing- stones, which are unusually large and well-coursed, stand to a height of 1.25m in four courses; elsewhere the wall is about 2.5m thick. Immediately SE of the entrance there is a short stretch of medial walling and on the NW the lowest course of the outer face is founded on a revetted platform, probably to give it greater stability. The entrance, which lies on the NE, was modified in antiquity, reducing its width from 1.8m to 1.4m. In the interior there are the footings of two enclosures and a stretch of ruined wall, all of which are of comparatively recent date.
The area to be scheduled measures up to 95m from E to W by 65m transversely, to include the fort and an area around in which associated remains may survive, as marked in red on the attached map extract.
