The monument comprises the remains of a hillfort which probably dates to the Iron Age period (c. 800 BC - AD 74). The rather complex plan of the hillfort suggests that it may be the result of more than one period of construction. First, in the middle is a sub-rectangular enclosure of almost 1ha, surrounded by a massive bank, with an external ditch on all but the north side, and an outer, couterscarp bank along the south. A straight stretch of rampart adjoins the west side, at a slight angle to it. The awkward way these merge towards their north ends suggests that the inner enclosure may have been superimposed on this outer rampart. Beyond is another outer rampart on all but the steep north side. A further, straight rampart runds north-south across the saddle of the hill to the west, giving extra protection from this, the most vulnerable side.

The entrance, a simple gap, is on the east side, with an entrance way bounded by low banks running up to the fort through a series of outer banks and the main outer rampart. Just inside, a low bank and outer ditch delineate a small rectangular enclosure, with a gap near the main entrance, which may be an earlier enclosure or an animal annexe. To its west is the probable position of a circular house platform.

The monument is of national importance for its potential to enhance our knowledge of later prehistoric defensive organisation and settlement. The site forms an important element within the wider later prehistoric context and within the surrounding landscape. The site is well preserved and retains considerable archaeological potential. There is a strong probability of the presence of evidence relating to chronology, building techniques and functional detail.

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