The structure is only nine metres across, yet the effort involved in its construction is legible in the ground itself: the western side has been cut into the hillslope to a depth of around 1.55 metres, while the excavated material was presumably used to raise the eastern side to roughly 1.6 metres, creating a pronounced interior depression through a deliberate cut-and-fill technique. The result is a sunken bowl of earth, walled on one side by the hill and banked on the other, with what appears to be an entrance gap of about two metres on the northern side. An old trackway runs along the southern flank, visible on the Ordnance Survey six-inch map.

What makes the site particularly interesting is its possible relationship to a larger complex of earthworks a short distance away. Around seventy metres to the west sit a cliff-edge fort and a further enclosure, and this smaller structure may have functioned as an outpost associated with that grouping. A cliff-edge fort is exactly what the name suggests: a defensive or enclosed site positioned at the edge of a natural drop, using the cliff itself as one side of its boundary. The outpost enclosure, if that is indeed what this is, would have occupied a forward position on the slope, keeping a line of sight down and across the terrain below. Whether it served a defensive, agricultural, or ceremonial function is not recorded, and the woodland that now surrounds it has long since softened any sense of strategic exposure it might once have had.
