This monument consists of a well-preserved hut circle, partly covered with modern field-clearance stone, set within an irregular, curvilinear enclosure which runs around the top of a natural hollow. The hut circle is in the bottom of the hollow, and is about 9m in diameter. The larger enclosure measures about 53m NNE-SSW. To the N,S, and E are field banks which define part of a once extensive early field system associated with the enclosure. The monument is of national importance for its potential to enhance our knowledge of prehistoric settlement. It retains significant archaeological potential, with a strong probability of the presence of associated archaeological features and deposits. The structures themselves may be expected to contain archaeological information concerning chronology and building techniques.

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