The monument comprises the remains of two earthen built round barrows, which probably date to the Bronze Age (c. 2300 - 800 BC), and an earthwork enclosure, the date of which is unknown but is likely to be later prehistoric or medieval. The barrows lie at the north-eastern end of the hilltop, are circular in shape on plan and have a rounded profile. Barrow A, the more northerly of the two, is c.10m in diameter and c.0.6m high, and has been cut into on the north at some point in the past. Barrow B, a short distance to its south, is c.10m in diameter and c.0.7m high, with a central disturbance said to relate to activities during World War II. To their south-west, at the opposite end of the hilltop, Enclosure C appears to consist of two elements. The first is a sub-circular enclosure c.32m in diameter internally, defined by two banks, each c.0.7m high, with a ditch between them c.1.5m deep and a simple entrance gap at the north-east. Adjoining this on its south-east is a sub-rectangular annexe measuring c.35m north-west to south-east by c.24m, enclosed by a bank c.1m high and an external ditch c.0.5m deep.

The monument is of national importance for its potential to enhance our knowledge of prehistoric burial and ritual practices and of later prehistoric or medieval settlement and defence. The features are important elements within the wider landscape and retain significant archaeological potential. There is a strong probability of the presence of both intact ritual and burial deposits, together with evidence covering the environment, chronology, construction techniques and functional detail. Barrows and enclosures may be parts of a larger cluster of monuments and their importance can be further enhanced by their group value.

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