This earthwork enclosure sits on level pasture and takes the form of a rough rectangle, stretching approximately 45 metres from east to west. Though centuries of weathering have taken their toll, the site still retains traces of its original defensive features: an earthen bank, now mostly reduced to a simple scarp, and an outer fosse or ditch that once helped protect those within.

The best preserved sections of the defensive works can be found along the western side, from the southwest corner round to the northwest, where both the bank and the three-metre-wide external fosse remain visible. The bank itself, originally perhaps an imposing barrier, now stands just half a metre high on its outer face and 30 centimetres on the inner side, with a width of about one metre. The southeastern section shows signs of later alteration, suggesting the site may have been modified over its long history.

Perhaps the most intriguing feature lies in the enclosure’s northwest sector, where archaeologists have identified what appears to be either a collapsed souterrain or a well. This underground passage measures 4.5 metres long and nearly two metres wide, plunging two metres into the earth. Its drystone walls still stand five courses high in places, though there’s no evidence that it ever had a roof; the passage remains open to the sky and waterlogged, preserving this mysterious medieval feature for future generations to puzzle over.
