It is this kind of quiet indignity that tends to befall Ireland's raths, and the example at Ballydonnell in County Limerick is a fairly typical casualty of centuries of agricultural reorganisation. The wonder is not that it survives in this condition, but that it survives at all.

A rath, broadly speaking, is a circular earthen enclosure dating to the early medieval period, roughly the fifth to twelfth centuries, and was most commonly used as a farmstead or defended homestead. The Ballydonnell example sits in level pasture and measures twenty-four metres in diameter, defined by a sequence of features that would once have formed a coherent defensive or boundary system. The innermost edge is a scarped lip, very slight on the interior at around five centimetres but rising to thirty-five centimetres on the outer face. Beyond that lies a fosse, a roughly two-metre-wide ditch cut into the ground, and then an external bank that stands about thirty centimetres on its inner face and tapers to ten centimetres on the outside. These are modest dimensions by the standards of some raths, but the layered logic of the earthworks, scarp, fosse, bank, is still legible if you know what to look for. The record was compiled by Denis Power and uploaded in August 2011.

The site sits in what is now ordinary grazing land, and the interior remains level and under pasture, which at least means the ground has not been ploughed out. The east-west field boundary and drain that divide it are the most visually disruptive elements; they make it harder to read the enclosure as a whole from within. Walking the perimeter, however, the circular logic of the earthwork becomes clearer, and the slight external bank, though low, holds its shape. There are no formal access arrangements noted for the site, so as with most field monuments of this kind in Ireland, a view from a public road or lane is the most that can reasonably be expected without the landowner's permission.
