The monument comprises the remains of an earthwork enclosure. The date or precise nature of the enclosure is unknown, but it is likely to be later prehistoric or medieval. It lies on a south facing slope, is sub-rectangular and measures c 67m north west to south east by c 48m although the circuit is only fully visible on aerial photographs as it has been plough-reduced. The bank is best preserved on the south side where it is about 0.15m high above a scarp of c 3m. An entrance has been recorded in south east and a there is possible outer defence 65m to the north. A sword is reported to have been found at the base of slope to the south.

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.
