The structure is a rath, the earthen variety of ringfort, a class of monument built across Ireland roughly between the early medieval period and the Viking Age, typically enclosing a farmstead and its associated buildings. What gives this particular example a quietly layered quality is not its size, which is modest at around twenty-two metres in diameter, but the degree of complexity preserved beneath the bramble and grass.

The enclosure is defined by a bank roughly six metres wide, rising to an external height of about 3.2 metres in places, though the interior face is considerably lower, between 0.35 and 1.1 metres above the ground within. A fosse, or defensive ditch, runs around much of the circuit, visible from the west-north-west around through the south. Beyond that ditch there is an outer bank, lower and narrower but still traceable along the same arcs of the perimeter. This double-bank and fosse arrangement, known as a bivallate plan, suggests the enclosure was considered worth a degree of extra effort and perhaps extra status. The interior is level but wet. Near its eastern side there is a blocked-up feature identified as a possible souterrain, an underground passage or chamber, often stone-lined, that in an active ringfort would have served for storage or concealment. A probable entrance opening, about 2.2 metres wide, faces east-south-east, and a later cattle-break has been made through the western bank, a small domestic edit that speaks to centuries of agricultural reuse long after the original purpose was forgotten.
