The monument consists of the remains of a castle, dating to the medieval period. Some form of keep may have stood within the enclosure but these were not significant in defensive terms and served mainly to provide accommodation. The Tudor manorhouse at Pencoed was probably built during the early 16th century by the Morgan family, on the site of a moated Norman castle and may incorporate part of the earlier castle. The family resided at Pencoed until the end of the 17th century and later come under the ownership of the Gwyns of Llanhowell. The castle is surrounded by a rectangular moated enclosure with the remains of a 13th or 14th century curtain wall and at least one circular tower located at the southwest corner and linked to the gatehouse. Excavation has revealed evidence for a range of buildings along the north side of the courtyard.

The monument is of national importance for its potential to enhance our knowledge of medieval defensive practices. The monument is well-preserved and an important relic of the medieval landscape. It retains significant archaeological potential, with a strong probability of the presence of both structural evidence and intact associated deposits.

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