At Dooncaha in County Limerick, what was once a substantial oval mound, roughly fifteen metres along its longest axis and ten metres across, has been levelled out of existence. The land is pasture now, and the hill slope carries no obvious sign that anything deliberate ever stood here. Almost nothing remains except a short arc of scarped edge, a term for the cut or trimmed face of an earthwork, running southeast to south-southeast. That remnant measures just over three and a half metres wide and rises to about a metre in height before being cut off at its lower end by a field boundary.

The mound's former shape is known primarily because it was recorded on the Ordnance Survey six-inch map of 1923, which captured the monument as a clearly defined oval before whatever agricultural activity reduced it to its current state. Denis Power compiled the site record, uploaded in August 2011, by which point the levelling was already complete and only that small scarped arc remained as physical evidence. Mounds of this general type in the Irish landscape can serve a variety of original purposes, from burial to ceremonial to territorial marking, though the notes here do not specify what function this particular example served, and it would be guesswork to assign one.

The site sits in pasture on a steep south-facing slope of a hill, which means the ground underfoot is likely uneven and can be slippery in wet conditions. The surviving scarped edge is subtle enough that a visitor without prior knowledge of its location might walk past without noticing anything at all. The field boundary that truncates the southern end of the arc is itself a kind of marker, worth looking for as a navigational reference. Given how little is physically present, the 1923 OS six-inch map sheet is arguably more informative than the site itself, and consulting it beforehand gives the visit a different kind of purpose, that of reading a landscape against a historical record and measuring what has since been lost.
