What gives it away, if you know what to look for, is the slight earthen bank that traces a near-perfect circle roughly forty metres across, and beyond that, the faint remnant of an outer fosse, the defensive ditch that once reinforced the whole arrangement. A rath is the Irish term for this kind of earthen ringfort, a form of enclosed farmstead that was the standard unit of rural settlement in early medieval Ireland, typically dating to somewhere between the sixth and twelfth centuries. Most were home to a single farming family, with the enclosing bank and ditch serving as much to mark territory and social status as to provide serious military defence.

The earthworks here are modest but legible. The enclosure rises about a metre above the surrounding ground at its highest, with the bank better preserved along the southern arc, where its base spreads around six metres wide, than along the northern side, where it has weathered down to a simple scarp. The outer fosse survives as a berm, a flat shelf of ground between the inner bank and an outer scarp, running from the west around to the north-east before it is cut off abruptly by a later field boundary running north-west to south-east. That field bank is the kind of intrusion that accumulated over centuries of agricultural reorganisation, quietly erasing the older geometry. No original entrance to the enclosure has been identified, which is not unusual where erosion and later land use have smoothed the approaches beyond recognition.
