  The monument consists of the remains of a castle, dating to the medieval period. Penmark
  is a substantial 13th century castle. A round tower stands to second floor level and a stretch
  of hugh curtain walling of the inner ward runs southwards from it. Fragmentary remains of
  other parts, with a large outer ward to the west. The castle was held by the de Umfreville
  family and then by the Bawdrips.

  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.'
