Most ringforts in Ireland occupy commanding high ground, placed where their occupants could survey the surrounding landscape. This one, in Glen, County Waterford, does the opposite. It sits towards the bottom of a steep north-facing slope, tucked into mixed woodland, an arrangement that makes it quietly anomalous among its kind.

A rath is an earthen ringfort, the most common monument type surviving in the Irish countryside, typically dating from the early medieval period roughly between the fifth and twelfth centuries. They served as enclosed farmsteads, the bank and fosse providing a degree of security for a family and their livestock. Here, the enclosure is subcircular, measuring approximately 33 metres northwest to southeast and 28 metres northeast to southwest. The earthen bank, between three and four metres wide, still stands to an internal height of around 1.5 metres at its southwestern stretch, though downslope to the north and east it has been worn back to little more than a scarp. Outside the bank ran a fosse, a shallow external ditch, which survives in places as a low berm, a narrow level shelf of ground, though it too has been considerably reduced over time. Where the entrance once lay is no longer clear. The bank and fosse between the northeast and southeast have been destroyed, and it is thought the original opening may have been somewhere in that arc, though nothing definitive remains to confirm it.
