There is considerable medieval activity on the site, including a probable 14th century building, possibly overlying an earlier structure. Documentary evidence suggests a tower or some building of considerable significance stood on the boss of rock at this site during the 13th century.

The monument is of national importance for its potential to enhance our knowledge of medieval 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.
