The monument comprises the remains of a motte and ditch, dating to the medieval period (c. 1066 -1540 AD). A motte is a large conical or pyramidal mound of soil and/or stone, usually surrounded by either a wet or dry ditch, and surmounted by a tower constructed of timber or stone. Cwm Camlais comprises a large steep sided motte surrounded by a ditch and outer bank. The motte is 6m high and is surmounted by a masonry tower, the remains of which can be seen lining the sides of a hollow in the summit. The ditch is 2.5m wide and up to 2.5m deep with a causeway on the SW side, although this may be a modern feature.

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.
