A rath, the Irish term for a roughly circular earthwork enclosure typically used as a farmstead in the early medieval period, usually announces itself through a raised bank and ditch. Here, the bank has gone entirely, and what remains is a faint arc curving from northwest to south across pasture on a northeast-facing slope, the rest of the circuit swallowed by later agricultural activity.

The discrepancy between two nineteenth-century Ordnance Survey maps offers a quietly telling detail. The 1846 six-inch map records the enclosure as a roughly circular feature approximately twenty-five metres in diameter. By 1894, the same survey series shows it larger, at around forty metres across, though by that point a field boundary had already cut across the southwestern side. Whether the earlier survey underestimated the size or the later one captured a fuller picture before further loss, the field boundary that truncates the southwestern arc had clearly begun to assert itself. Today there is no trace of any bank on that southwestern side, suggesting the boundary did not merely cross the rath but effectively erased that portion of it.
