The monument comprises the remains of a motte and bailey castle, a military stronghold built during the medieval period. The site is located within Trecastle Farm, with the bailey largely built over by farm buildings. The motte is a large steep-sided mound, 6m high, with a flat top that is 15m in diameter. On the N side there is a steep sided ditch, 3m wide and 2.5m deep, which peters out at the W and E sides. On the S side the base of the motte has been truncated by a modern retaining wall. To the S of the motte, separated from it by buildings and a drive, is a substantial bank 1m high on the N side and 3m high on the S side, which forms part of the original bailey defences.
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.
