The monument comprises the remains of an earthwork with the best preserved sections to the north and west comprising double concentric banks with an internal ditch. The date or precise nature of the enclosure is unknown, but it is likely to be later prehistoric.

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. It is oval in shape and measures approximately 105 metres N-S by 131 metres E-W.
