This is a rath, the most common type of ringfort found across Ireland, typically a circular or oval enclosure defined by an earthen bank and ditch that once served as a farmstead during the early medieval period, roughly between the fifth and twelfth centuries. What makes this one worth pausing over is how much of its original form has quietly endured, even as the land around it has been reclaimed almost to its very base.

The enclosure measures roughly 42 metres east to west and 34 metres north to south, rising about two metres above the general slope of ground that climbs away from the Nore to the east. The defining bank, composed largely of clay-rich gravel and studded with protruding boulders along its outer face, survives most clearly in the eastern and western quadrants, where it still stands nearly three metres high on the exterior. No fosse, the ditch that typically runs outside such a bank, is visible today; agricultural activity has been taken right to the foot of the enclosure. A steep ramp on the west-north-west side, five metres wide, may mark the original entrance, though it could equally be a later addition. The southern sector has fared less well, disturbed over time by tree planting, quarrying, and rubbish disposal, all the ordinary pressures that gradually erode earthworks when they lose whatever symbolic or practical protection once kept them intact.
