The monument comprises the remains of an earthwork/stone-built enclosure as well as extensive and unusually well defined associated field boundaries, dating from the Iron Age or Romano-British periods (c. 800 BC - AD 400). The enclosure is particulary well preserved and the absence of stone features within the interior might suggest that it once contained timber structures. Alternatively it may have served as an enclosure for livestock. Other monuments of similar date have also survived in this area.

The monument is of national importance for its potential to enhance our knowledge of later prehistoric defensive organisation and settlement. 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 site forms an important element within the wider later prehistoric context and within the surrounding landscape. Taken together with the other monuments of similar date in this area the site also has considerable group value.

The scheduled area comprises the remains described and areas around them within which related evidence may be expected to survive.
