The monument comprises the remains of an earthwork/stone-built enclosure. The date or precise nature of the enclosure is unknown, but it is likely to be later prehistoric or medieval. A single bank and ditch enclose a roughly rectangular area. The bank is about 12' above the exterior and 5' above the interior. The ditch is best preserved on the north-east where it serves as a field boundary, but it is largely filled in on the south-east and south-west. The ground falls steeply on north-west.

The monument is of national importance for its potential to enhance our knowledge of later prehistoric defensive organisation and settlement. The site forms an important element within the wider later prehistoric context and within the surrounding landscape. The site is well preserved and retains considerable archaeological potential. There is a strong probability of the presence of evidence relating to chronology, building techniques and functional detail. The scheduled area comprises the remains described and areas around them within which related evidence may be expected to survive.
