The ringfort at Piercefield sits on a north-west facing hillside, with open views to the west and north and a ridge rising behind it to the south-east. Ringforts, known as raths when formed from earthworks rather than stone, were the enclosed farmsteads of early medieval Ireland, typically dating from roughly the fifth to the twelfth century. Most were home to a single family and their livestock, defined by a circular bank and ditch that offered both social status and a degree of protection.

This particular example is sub-circular, measuring approximately 35 metres north to south and 34 metres east to west. Its earthen bank is poorly preserved, and the surrounding fosse, the ditch that runs alongside the bank, survives only in parts. What makes the arrangement here slightly unusual is its double-ditched structure: an inner fosse, best visible along the southern and eastern arc, is separated from a shallower outer fosse by an intervening space roughly 5.5 metres wide. A possible entrance gap, about 2.2 metres across, can be read at the north-east. Inside, the ground slopes gently and retains faint traces of broad cultivation ridges, suggesting the interior was worked as agricultural land at some point, perhaps long after the fort itself fell out of use. A rectangular mound within the enclosure may represent the collapsed remains of a house site, though the ground has been further cut across by a field drain to the north-east and a field fence on the south-west, both of which intersect the monument's original perimeter. About 600 metres to the west-south-west lies Templeoran Church and its associated graveyard, a proximity that hints at the overlapping rhythms of secular and religious settlement across this particular stretch of the midlands.
