The one at Lisheenanoul breaks that pattern quietly: it sits in what was once marshy, low-lying terrain, reclaimed at some point into the flat pasture that now surrounds it. The choice of such a setting is not without precedent, but it does prompt curiosity about what drew a community here and how the land looked when the site was in use.

A ringfort, or rath, is an enclosed farmstead of the early medieval period, typically defined by one or more earthen banks and ditches. The Lisheenanoul example is modest in scale, a circular area roughly 23 metres in diameter, defined by a bank that has been considerably worn down over time. The crest of that bank measures about 4.4 metres wide and the base around 7.6 metres, though the structure has flattened to little more than a low scarp, standing under a metre in height. There is also a faint trace of what may once have been an outer fosse, the shallow ditch that would have ringed the bank and added a further line of enclosure. A stream runs approximately 100 metres to the north-west, which likely made the location practical for whoever farmed here, despite the waterlogged ground. Today the whole feature is grass-covered, blending into the reclaimed pasture around it almost entirely.
