Cadw's description
Summary description and reason for designation
The following provides a general description of the Scheduled Ancient Monument.
The monument consists of the remains of a dyke, a defensive boundary or earthwork, dating to the later prehistoric or medieval period. It measures approx. 155m long, running east-west across the top of the ridge on open moorland. It comprises a ditch with turf-covered banks on both sides, the northern one being somewhat slighter than that on the southern side. The northernmost bank measures 1.2m high and the southern 1.5m high.
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.
