This rath, or earthen ringfort, sits roughly a hundred metres north of the townland boundary in Bulcaun, its circular outline still legible in the landscape despite centuries of agricultural pressure and slow encroachment from hawthorn and blackthorn scrub.

Ringforts were the dominant settlement form in early medieval Ireland, typically enclosing a family farmstead within a bank and ditch, and this one follows the familiar circular plan: roughly 29 metres across at its widest, defined by a stony bank that is now little more than an earthen scrap topped with a sod-covered stony lip. The bank survives best on the northern side, where it still stands around 1.4 metres on the exterior face, tapering to a much lower profile at the south-east. A break of about two metres on the north-west side may mark an original entrance, though centuries of field use have complicated the picture. Inside, faint linear features running on a roughly north-south axis suggest the interior was at some point given over to cultivation ridges. The most affecting layer of the site's history, however, comes from local knowledge rather than physical remains. According to oral tradition, the interior was used as a children's burial ground. These informal burial sites, sometimes called cillíní, were used across Ireland, often within or beside ancient monuments, for unbaptised infants or others who could not be interred in consecrated ground. The practice imbued places like this rath with a different kind of sanctity, separate from the Church and carried instead through community memory. Heaps of field clearance stones beside the enclosure, and a field fence that partially merges with the outer bank, speak to the generations of ordinary agricultural work that continued around and over all of this.
