What once existed here was a souterrain, an underground stone-lined passage or chamber typically built during the early medieval period, often used for storage or as a place of refuge, and usually associated with a nearby ringfort. The trouble is that the ringfort it belonged to has been levelled, and the souterrain has left no visible trace on the surface either. The entire complex has effectively been absorbed back into the landscape.

What makes this site quietly peculiar is the position of the souterrain itself. When Bowman recorded it in 1934, it was noted as lying on the outside of the ringfort's rampart rather than within the enclosure, which was the more common arrangement. A ringfort is a roughly circular enclosed settlement, typically defined by one or more earthen banks and ditches, and souterrains were usually tucked inside that defensive boundary. Finding one positioned beyond the rampart raises questions that, with the site now gone, are unlikely to be answered. Bowman's brief note from 1934 is essentially all that survives as documentation of the feature's precise character and location.
