The monument consists of the remains of a castle, dating to the medieval period. A castle is a defended residence or stronghold, built mainly of stone, in which the principal or sole defence comprises the walls and towers bounding the site. Some form of keep may have stood within the enclosure but these were not significant in defensive terms and served mainly to provide accommodation. Dolforwyn Castle is situated above the village of Abermule. The fortification was established by Llywelyn ap Gruffudd, Prince of Gwynedd in the late 13th century. It is sited on a wooded ridge commanding excellent views of the upper Severn Valley. The original castle consisted of a rectangular keep at the south west end of the platform and a circular tower at the opposite end. The two structures were subsequently connected by ramparts to make a rectangular shaped enclosure with a D-shaped tower on the northern wall. The enclosed area was divided into two wards by a rock-cut ditch. A two-storey structure was built against the north wall. The main gateway into the castle was in the west wall. A smaller entrance was sited in the south wall.

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.
