Cadw's description

The following provides a general description of the Scheduled Monument.

A rectangular enclosure on a small rocky hill, probably dating to the later prehistoric period. The enclosure measures 38m by 35m and is demarcated by a rubble wall 3m thick, which was faced with large orthostats. The remains of the entrance can still be seen on the NE side, where one large gatepost survives. The enclosure wall has been used as a stone dump and is surmounted, in places, by a modern stone wall. The SW wall has been largely robbed out. There are vague traces of a rectangular building in the SE corner.

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.
