The monument comprises the remains of a motte and bailey castle, a military stronghold built during the medieval period, located on the top of the Wentwood ridge overlooking the coastal plain to the SE and the Usk valley to the NW. The motte comprises a circular mound, 25m in diameter and 2m high with steep sides and a summit 7m in diameter. A rough track cuts across the site immediately to the NW of the motte. The large bailey (c. 3 acres) surrounds the motte, and consists of a flat, roughly circular area defined by a bank. On the NE, N and NW sides there is an external flat bottomed ditch, 4m wide and up to 1m deep, with a low external bank, 1.5m high. There is no ditch visible on the S side. There is some debate about whether the site is indeed medieval in origin, and suggestions have been made that it is in fact a prehistoric enclosure.

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.
