The monument comprises the remains of a motte and ditch, dating to the medieval period (c. 1066 -1540 AD). The motte lies at the top of a steep slope down to the valley of the Dowlais Brook. It is a large oval tree covered mound with steep sides and a flat top. It is 4m high, and the top measures 13m by 22m. On the N side there is a narrow flat berm before the ground drops very steeply to the valley floor, where there is a car breakers' yard. On the W side there is a ditch 2m wide and 1m deep. This continues round to the S side where it becomes shallower - 0.3m deep. Towards the E end on this side the outer edge of the ditch has been artificially cut to form a near vertical slope and continues round the E side as a garden wall.
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.
