Dating from the medieval period, this defensive earthwork measures an impressive 50 metres northeast to southwest and 68 metres northwest to southeast overall. The site consists of a raised square platform, roughly 27 by 37 metres, surrounded by a substantial earth and stone bank that would have originally stood as a formidable barrier. The bank itself has a base width of 5 to 6 metres, narrowing to about 1.7 metres at the top, and still rises between 1 and 3 metres high despite centuries of weathering.

The defensive capabilities of the site are enhanced by a wide, flat-bottomed external fosse, or ditch, that runs around the perimeter. This water-filled moat would have been approximately 4.3 metres wide at its base, expanding to 6.5 metres at the top, with a depth of around 2 metres; quite a deterrent for any unwelcome visitors. What appears to be the original entrance survives as a 1.9-metre gap in the bank at the northeast corner, though a more recent breach has been made at the southwest, likely for modern agricultural access. The interior platform sits level with the surrounding ground, and whilst now overgrown, it would have once contained the timber or stone buildings of whoever controlled this stronghold.

The site's strategic importance is underscored by its proximity to other medieval fortifications in the area, including another possible moated site just 308 metres to the southeast and a tower house 200 metres in the same direction. These clustered defensive structures suggest this was once a significant area of control and settlement during the turbulent medieval period. Historical maps from 1903 show field boundaries that once crossed through the northern section of the monument, though the boundary running south from the southeast corner has since been removed, helping to preserve the site's impressive circular footprint.
