  Period

  Medieval

  The monument comprises the remains of a medieval hall. The surviving wall of the hall block
  may be dated to the late 13th century, but the first substantive period of building dates
  to the 15th century. Measuring approximately 4m high, it runs NNW-SSE and is 1-1.2m thick.
  At the northern end is a large fireplace, there is another at the midpoint along the wall,
  and in the southern end there is another blocked fireplace c. 2.2m high with a small oven
  built into the wall.

  The monument is of national importance for its potential to enhance our knowledge of medieval
  secular architecture. The monument is a well-preserved example of its type and forms an
  important element within the wider medieval context. The structure itself may be expected
  to contain archaeological information in regard to chronology, building techniques and functional
  detail.

  The scheduled area comprises the remains described and areas around them within which related
  evidence may be expected to survive.'
