  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. The remains of Ystrad-Meurig Castle consist of a rather
  angular enclosure, about 100m north-south by 82m, occupying the southern tip of a spur.
  This has traces of a rampart and ditch on the north where it faces level ground and is otherwise
  defined by scarps above steep natural slopes. In the northern part of the enclosure are
  the foundations of a massive rectangular stone tower, 18-20m across. This was apparently
  part of a building complex at least 30m across. Within the south-western corner of the castle
  enclosure, gentle scarps define an inner oval enclosure, about 35m north-south by 30m. The
  castle was established in about 1110 and then destroyed in 1137. It was disputed, besieged
  and rebuilt through the later twelfth century and is last recorded in 1208. It is possible
  that earlier notices refer to a castle mound 1.6km to the east (SAM CD031).

  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.'
