The monument comprises the remains of an earthwork dating to the early medieval period. The earthwork is situated on top of a ridge, in dense woodland, south of Cwm George camp (GM023). It consists of two parallel banks and ditches running south-west / north-east across the ridge, starting on the western side at the edge of the steep slope which descends to Cwm George. The outer (northernmost) bank stops in the middle of the ridge and the inner most one turns abruptly to the south-east and continues, with an outer ditch, in this direction a short way before petering out. On the south-west / north-east section the outer ditch is 3m wide and 1m deep on the outside. The bank (outer) is 2m high on the ditch side and 1.5m high on the inside, with steep sides. There is then a gentle slope of 12m before another ditch 3m wide and 0.6m deep, and another bank 1.2m high on the ditch side and 1m high on the outside. On the north-west / south-east section the bank is 1.5m high, with steep sides, and the outer ditch is 2.5m wide and 0.3m deep.

The monument is of national importance for its potential to enhance our knowledge of early medieval settlement. The monument forms an important element within the wider early medieval context and the scheduled area may be expected to contain a wide range of archaeological information, including chronological detail and evidence in regard to construction techniques and settlement activities.

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