This is a rath, one of the thousands of early medieval ringforts scattered across Ireland, typically dating from roughly the sixth to the tenth century and serving as enclosed farmsteads for a single family or small community. The bank here is modest, rising only about 0.45 metres on the interior and 0.8 metres on the exterior, and measures around 30 metres across. Numerous cattle gaps have been knocked through the earthwork over the years, and the interior is now thick with long grass, briars, and nettles.

What gives this particular site a quiet layer of interest is the souterrain recorded in its south-eastern quadrant. A souterrain is an underground stone-lined passage or chamber, usually associated with ringforts and thought to have served for storage, refuge, or both. The field in which this rath sits has its own telling name: Bowman, writing in 1934, recorded it as Pairc a Leasa, meaning Fort Field in Irish, a piece of local nomenclature that suggests the earthwork has been a recognised feature of the working landscape here for generations. Even as the bank has worn down and the briars have moved in, the name endured, passed along by the people farming around it.
