Roughly half of the enclosure's perimeter relies not on built earthwork but on the sheer natural drop of a watercourse, a practical economy that tells you something about how these sites were actually constructed and chosen. The earthen bank, standing about a metre high, handles the arc from northwest around to south-southwest, while the stream bank completes the circuit in the opposite direction, stone-faced in places where the builder apparently felt the natural edge needed reinforcing.

The enclosure itself is nearly circular, measuring just under thirty metres across in both directions, which places it in the middle range for a rath. A rath is simply the Irish term for a ringfort built from earth rather than stone, a type of enclosed farmstead that was the standard unit of rural settlement across Ireland during the early medieval period, roughly the fifth to twelfth centuries. Most were home to a single farming family, the bank and ditch providing a degree of security for livestock as much as for people. What lifts this particular example slightly out of the ordinary is the souterrain recorded in its northeastern quadrant. A souterrain is an underground passage or chamber, typically stone-lined, built beneath or adjacent to the interior of a ringfort. Their exact purpose is still debated, but they are generally understood to have served for storage, refuge, or both, and their presence usually signals a site of some substance rather than a minimal or temporary occupation. The combination here, a carefully adapted natural boundary, partial stone facing, and a subterranean structure, suggests a settlement that was put together with some deliberateness, making use of what the slope and the stream already offered.
