A rath, as this type of earthwork enclosure is known, would originally have consisted of a raised circular or oval bank of earth or stone enclosing a domestic settlement, typically dating from the early medieval period. This one has been levelled, its banks absorbed into the surrounding tillage field, its only remaining physical trace a scatter of stone spread across the soil and fragments of iron slag, the waste material left behind by metalworking.

What makes this site quietly compelling is that its disappearance can actually be tracked across a sequence of Ordnance Survey maps. On the 1842 six-inch map, the fort still registered as an irregular-shaped field, its southern edge already cut across by an east-west trackway. By 1904, only an arc of hachures remained on the map, running roughly north-north-west to south-south-east, the cartographic shorthand for an earthwork in decline. By 1936, the arc had shifted further, running south-south-west to south-south-east, and by that point the structure was clearly fragmentary. Sometime after that, it vanished entirely from the landscape, leaving no surface trace. The iron slag recovered from the field is a small but telling detail; metalworking was a skilled and valued activity in early medieval Ireland, and its presence suggests this was once a settlement of some local significance, not merely a simple farmstead enclosure.
