Description

The monument consists of the remains of a dyke, a defensive boundary or earthwork, dating to the early medieval period. The scheduled area of dyke is divided into two sections. The northern, longer section which is c.560m long, extends from a point on the north-facing slope overlooking the upper reaches of Cwm Mule, to a point on the south-facing slope overlooking Iyrchyn. The second shorter section (c.180m) is on the north-facing slope overlooking Iyrchyn and the source of the River Teme, and terminates on the ridge above It is not clear if the two sections were once continuous. The dyke takes the form of double banks with a central ditch, or possibly a single bank, with ditch to the west and then a counterscarp.

The monument is of national importance for its potential to enhance our knowledge of later prehistoric/medieval defensive organisation and settlement. It retains significant archaeological potential, with a strong probability of the presence of associated archaeological features and deposits. A dyke may be part of a larger cluster of monuments and their importance can further enhanced by their group value.

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