A rath is an early medieval earthen ringfort, a type of enclosed farmstead once numbering in the tens of thousands across Ireland, and this one carries a detail that lifts it out of the ordinary: a cup-marked boulder lying in the fosse to the east-southeast. Cup marks are shallow, circular depressions pecked into stone, and they belong to a tradition far older than the ringfort itself, typically associated with prehistoric activity. The boulder's presence in the ditch raises quiet questions about the relationship between the people who made those marks and whoever later chose this same ridge to build their enclosure.

The ringfort itself is a circular area enclosed by an earthen bank standing around 1.25 metres high, stone-faced in places, with an external fosse roughly one metre deep. That combination, an earthen rampart with at least partial stone facing and a surrounding ditch, suggests a reasonably substantial construction effort for what was most likely a defended farmstead of the early medieval period. The interior is heavily overgrown, with a small waterlogged clearing to the north. There is also a possible souterrain on the site, a souterrain being an underground stone-lined passage typically used for storage or as a place of refuge, though its presence here has not been confirmed with certainty.
