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 (c. 800BC - AD74). The site is situated on open moorland on the top of a ridge near an east-facing scarp. The enclosure is roughly circular in shape, measures approximately 30m in diameter and was bounded by a palisade. Within the enclosure a small platform c. 6m in diameter contained the remains of a hut.
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.
