A ringfort, or rath, is a roughly circular enclosure of earthen banks used as a farmstead during the early medieval period, typically between the fifth and twelfth centuries. This one sits on a natural hillock on a gradual west-facing slope, looking out over a boggy valley floor. The earthworks have been levelled, the northern sector has been quarried away, and yet a low raised area, barely three-quarters of a metre high, still traces the outline of what was once an oval enclosure roughly twenty-nine metres across.

The site was documented as early as the first edition Ordnance Survey six-inch map of 1840, which showed it as a clear oval enclosure. By the time the revised edition appeared in 1904, only a hachured outline remained, and the eastern quadrant had already been lost to the record entirely. At the southern and western edges, there is still a suggestion of an outer fosse, a defensive ditch that would originally have encircled the enclosure, its width running to around four metres where traces survive. The combination of the elevated natural hillock, the boggy ground below, and the outer ditch suggests the site was chosen and shaped with some care, whatever modest farming household once occupied it.
