The five camps on the site are discussed below as individual Items. The three more westerly camps, lie in long, rough grassland which is lightly grazed; the remaining two, lie in heathland, with a cover of rougher vegetation.

ME077A This camp has only two sides were visible, as a ditch with a clear rounded corner, about 0.6m deep. The site lies in rough tussocky grass which is lightly grazed.

ME077B The area containing this camp is covered in rough heathy vegetation and is clearly undisturbed.

ME077C The eastern side of this camp is the clearest, though most of the circuit can be distinguished; the northern and southern ends are the faintest.

ME077D Some traces of the western defence could be seen in the heathy vegetation. The area clearly remains undisturbed.

ME077E The south-western and south-eastern sides of this camp are the clearest, the north-eastern side less so, and the north-western has long been damaged by drainage work.

The monument is of national importance for its potential to enhance our knowledge of Roman rule and invasion. It retains significant archaeological potential, with a strong probability of the presence of associated archaeological features and deposits. The structures themselves 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.
