A low ridge in County Limerick holds a roughly circular earthwork, around 22 to 25 metres across, whose bank is not uniform at all. It is strongest on the north-west to north-north-east arc and fades as it sweeps south and west, where it becomes little more than a scarp, a slight drop in the ground rather than any proper raised bank. That unevenness is not damage, or not only damage; it suggests a deliberate variation in effort, or perhaps in function, depending on which side needed defending or which faced the prevailing weather.

This is a rath, the Irish term for a ringfort, which was the standard form of enclosed farmstead across early medieval Ireland, typically associated with the period between roughly the fifth and twelfth centuries. They are common in the landscape but rarely identical, and the details here are particular. An external fosse, a shallow ditch roughly 1.25 metres wide and 0.4 metres deep, runs around the north-west to north-north-east section, reinforcing the bank at its strongest point. A gap of about two metres at the east-south-east marks what was almost certainly the original entrance. The interior is divided, its eastern third separated from the rest by a low internal bank running roughly north-north-east to south-south-west, a feature that hints at different uses for different parts of the enclosed space, whether for animals, storage, or domestic activity. The site sits on a west-facing slope just below the brow of a low ridge, a position that is characteristic of ringfort placement in Ireland, sheltered from the east but with a working view across the lower ground.

The site lies in pasture and the interior is currently masked by overgrowth, which makes close examination of the internal division difficult without some effort. The bank is most legible from the north-west side, where height and the accompanying fosse together give the clearest sense of the original enclosure. No formal access or signage is recorded, so a visit would depend on identifying the field and seeking landowner permission in the usual way. The measurements and survey notes were compiled by Denis Power and uploaded to the record in August 2011.
