  The monument consists of the remains of a medieval castle at Peterston. Comprising the north-west
  angle tower, it is the main surviving part of the castle of the le Sores of St Fagans and
  Peterston. Richard le Sore was settled in Glamorgan by c. 1102 and the family remained in
  possession until the site of the castle was sold to John Butler in c. 1382. There are possible
  traces of a 12th century keep, but the north-west tower is probably of 13th-14th century
  date. The surviving west wall stands to a height of c. 6m, with traces of north and south
  returns. The tower was of three floors. Of the uppermost only the beam holes of its floors
  remain. In the west wall is a splayed window with a segmented headed rear arch. There are
  traces of other windows at ground floor level in the north wall, and a garderobe chute in
  the south-west angle. Access between the floors was via a newel stair 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.'
