A small hillfort of 40 m by 25 m surrounded by a dry-stone wall. The interior is flat, grass-grown and unploughed. Remains of one round building survive and there appear to be the platforms of several others. The entrance is on the N and several structures occupy the slopes below the fort.

The monument is of national importance for its potential to enhance our knowledge of Prehistoric settlement and defence. 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.
