The monument comprises the remains of a medieval fortified manor house or castle of the De Malefant family. It is located on a gentle SW-facing slope, at 50m OD, overlooking Llanmaes Brook. It consists of a ruined rectangular masonry tower, which measures 14.4m NE-SW x 8.4m externally. The walls, built of lime-mortared Lias limestone rubble, are 1.5m thick. The most prominent surviving section, which stands to a height of 8.5m, includes the west angle, formed of dressed Sutton Stone and Lias limestone quoins, and adjacent section of the south-west wall. Adjacent to the west angle the northwest wall stands to a height of c. 8.5m for c. 2.5m. The remainder of the NW wall has been lost and replaced by a later boundary wall. The later wall does not follow the exact line of the medieval wall, but turns ENE across the predicted line of the tower wall. A 3m length of the footings of the medieval wall, which is not overlain by the later wall, is evident in the adjacent lawn. The south-west wall stands to a height of c. 8.5m for c. 4m from the west angle. The facing stone is pierced by putlog holes. Though the southern portion of the SW elevation has been lost, the RCAHMW Inventory describes the remains of a door bar socket indicating the location of a doorway in or adjacent to the (now lost) southern angle.

The monument is of national importance as a documented defended manorial residence of the Medieval period. The castle is an important element within the wider medieval context, demonstrating group value, and has the potential to enhance our knowledge of medieval landscape, settlement and organisation. The structure itself may be expected to contain archaeological information in regard to chronology, building techniques and functional detail. It has the potential to enhance our knowledge of medieval domestic and defensive architecture.

The scheduled area comprises the remains described and an area around it within which related evidence may be expected to survive. It is rectangular in shape on plan and measures 14.4m from NE to SW by 8.4m transversely.
