  Period

  Medieval

  The monument consists of the remains of a medieval castle situated on a knoll of high ground
  3.5km north-east of Cowbridge. It has artificially scarped slopes on all sides save the
  south, with a wide ditch running around the south, south-west and east. A curtain wall encloses
  the knoll and would have protected a keep and other associated castle buildings. It was
  strategically placed to protect the road running north from Cowbridge.

  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.'
