The monument comprises the remains of a motte and bailey castle, a military stronghold built during the medieval period. The site comprises a steep sided conical mound, 5m-6m high and 35m in diameter at the base. On the N side a large chunk of the mound has been quarried away, resulting in a 3.5m deep depression. The summit of the motte has partly been quarried away, with the surviving section measuring 12m NW/SE and 4m NE/SW. On the S and W sides are the remains of a shallow ditch, 3m wide and 1m deep. On the N side are the ephemeral traces of a bailey.

The monument is of national importance for its potential to enhance our knowledge of medieval defensive organisation. The well-preserved monument forms an important element within the wider medieval context and the structure itself may be expected to contain archaeological information 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.
