The site is divided into two parts by a modern field wall running across the site from E to W. The area to the N of this wall is heavily wooded, and the dense undergrowth makes part of the N rampart inaccessible. The majority of the visible archaeological remains is within this N area. The remains consist of a rampart 5-6 m wide faced with large boulders and with an inner core of stone rubble. This rampart has been damaged in a number of places, presumably by tree felling, and one of these damaged areas has been excavated.

The entrance was on the W side, just N of the present field boundary. The area is heavily overgrown, but the rampart would appear to divide into two, and then merge into a possible guard chamber. There is nothing visible on the S side of the entrance, and although it is presumed that the boundary of the fort followed the scarp S there are no surviving archaeological remains to confirm this on either the W or the E side.

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.
