Description
Summary Description and Reason for Designation
The monument consists of a sub-rectangular turf-built bank, c.0.6m high, c.26.5m N-S by 23.5m E-W, enclosing a level central area. There is a single entrance in the north. Excavation in 1961 showed the interior to be covered with a layer of rough metalling and divided by a central roadway. Four large posts at the entrance way are thought to have supported a tower.
The monument is of national importance for its potential to enhance our knowledge of Roman military operations in the area. The potential association with the early exploitation of metal ores in the area further enhances the importance of this site.
The scheduled area comprises the remains described and areas around them within which related evidence may be expected to survive.
