The monument consists of the remains of a length of Wat’s Dyke, a presumed 8th century AD defensive bank and ditch, divided in designation into two parts. The southern continuous section (A, B) extends for c.1160m to the north, west and south of The Lodge and Bryn Goleu houses within Erddig Park. Section (C) extends for c.200m and lies to the southwest of Erddig Mound and Bailey Castle (DE017),

The monument is of national importance for its potential to enhance our knowledge of early 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 be further enhanced by their group value practices.

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