The site appears as a low earthwork, forming two sides of a quadrilateral enclosure. The banks are some 25 m - 30 m long, and nearly 2 m wide. They appear somewhat less than 0.5 m high, nearer 0.3 m, implying the site has been ploughed in recent years.
The monument is of national importance for its potential to enhance our knowledge of Roman defence. It retains significant archaeological potential, with a strong probability of the presence of associated archaeological features and deposits. The structure itselves may be expected to contain archaeological information concerning chronology and building techniques.
The scheduled area comprises the remains described and areas around them within which related evidence may be expected to survive.
