A rath is a ringfort of earthen construction, typically dating from the early medieval period and used as a defended farmstead enclosure. This particular example is unusual in that it is not circular but U-shaped, its northern side apparently cut away by a deep natural gully or stream. What survives is an enclosure roughly 29.5 metres across east to west and 20 metres north to south, defined by a bank and an external fosse, the narrow, steep-sided ditch that once reinforced the bank's defensive profile. The eastern fosse narrows to just 0.6 metres at its base and drops 1.2 metres deep, suggesting the bank here was the most deliberately fortified face of the site.

The interior holds a layered history. A series of lazy beds, the long parallel ridge-and-furrow earthworks associated with pre-Famine potato cultivation, runs east to west across the enclosed ground, indicating that the site was brought back into agricultural use at some point well after its original purpose had been forgotten. More striking still is a deliberate terrace cut into the slope east of centre, on which the remains of a small house can be made out. The structure measures 7.5 metres long by 3 metres wide, defined by a low earthen bank with what may be an entrance gap on its north wall. Whether this building belongs to the original early medieval occupation or to a later, post-medieval phase of use is not certain, but its presence within a former ringfort is a reminder that these enclosures were often reused across centuries, their earthworks offering ready-made shelter and definition to later inhabitants. A secondary arcing bank also survives to the south of the main enclosure, sitting about 1.5 metres outside the primary bank and possibly representing an outer enclosure or annexe. A stone-lined entrance, 1.5 metres wide at the north-west, may be original to the rath's construction. The site was reported in 2013 by Ivor Kenny.
