  The following provides a general description for the scheduled ancient 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.    The monument consists
  of the remains of an enclosure approximately 48m north-south by 50m east-west sited on a
  spur-end between two streams flowing from west to east.  The enclosure is defined by a ditch
  on the west and elsewhere by steep natural slopes. On the west is an outer enclosure 72m
  north-south by 78m, again ditched on the west.  There is mention of a castle being built
  in this location in 1157 and captured in 1166.  Excavations concluded in 1957 demonstrated
  that an earthwork castle was replaced by a fortified manor house in the early thirteenth
  century which was itself abandoned in the late fourteenth century.

  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.'
