The rath at Ballysteen in County Limerick does the opposite. It occupies low-lying terrain at the edge of a marsh, a position that feels quietly contrary, and its interior slopes downward toward the centre, collecting whatever water the surrounding ground is willing to offer. It is the kind of site that prompts more questions than answers about who chose this particular hollow, and why.

A ringfort, or rath, is an enclosed farmstead of the early medieval period, roughly 500 to 1000 AD, typically defended by one or more circular earthen banks and ditches. The Ballysteen example is a bivallate fort, meaning it has two concentric banks rather than the single enclosure more commonly encountered. The inner bank stands up to 0.6 metres on its exterior face, while the outer bank is more substantial, reaching 1.4 metres on its outer side with a notably sheer external face. Between the two banks runs an intervening fosse, a flat-bottomed ditch about 2.7 metres wide, and beyond the outer bank lies a further external fosse some 3.3 metres across. At the western side, this outer ditch widens and merges with the marsh itself, suggesting the boggy ground may have served as a natural extension of the defensive circuit. The site was recorded and compiled by Denis Power, with details uploaded to the national record in August 2011.

The fort sits in rough pasture and shows the ordinary wear of agricultural land. A gap roughly four metres wide in the outer bank on the east-northeast side is probably not an original entrance; the surveyors noted it is likely the result of cattle pushing through repeatedly over many generations, and crucially there is no corresponding causeway or break in the inner bank to suggest it was ever a formal passage. Visitors approaching across the field will notice the outer bank's surprisingly clean external drop before the ground levels off into the intervening ditch. The interior, which dips toward a marshy centre, is best visited in drier summer months when waterlogging is less severe. There is nothing signposted or managed here; it is a working agricultural field, and access depends on local conditions and landowner goodwill.
