Cadw's description
Summary description and reason for designation
The following provides a general description of the scheduled monument.
The monument consists of the remains of a dyke, a defensive boundary or earthwork, dating to the later prehistoric/medieval period. This is a well-preserved linear earthwork running across a ridge, with a total length of approximately 500m. It has an average height of 3-4m rising to 5m at the western end. There is a ditch on the northern side which is up to 1.5m deep. There are slight traces of a ditch on the south side.
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.
