  The following provides a general description of the scheduled monument.

  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.'
