The feature is a rath, the Irish term for a ringfort, one of the most common early medieval monument types in Ireland. These were typically enclosed farmsteads, their raised banks and ditches defining a domestic space for a family and their livestock. This particular example is oval rather than perfectly circular, measuring roughly 27 metres along its longer axis, and the ridge-top position is deliberate; the natural fall of ground around it amplifies the height of the scarp, which rises between 1.5 and 1.7 metres, and especially on the northern half presents what is, in places, an almost vertical face.

The site appears on the 1838 Ordnance Survey six-inch map, where it is recorded as a circular enclosure of around 20 metres diameter, partly absorbed into a field boundary on the south-east side. It does not appear on later map editions, which suggests that at some point it ceased to be legible as a distinct feature to cartographers, even as the earthwork itself persisted. The interior carries a slightly domed profile, with a raised spine running roughly east-north-east to west-south-west and a noticeable slope downward toward the north-east and east. A level terrace, three to four metres wide, skirts the base of the scarp on the northern and eastern sides; whether this represents the remnant of an outer enclosing element, such as a second bank or ditch, remains uncertain. The core of the platform is compact, gravel-rich earth. The most likely original entrance was to the east, where the slope broadens and gentles, a practical choice that would have made daily movement in and out considerably easier.
