At Ballykevan in County Limerick, a circular earthen mound once sat on a flat-topped hillock in open pasture, measuring roughly twenty metres across. It was recorded on the Ordnance Survey's six-inch map of 1841, noted in the accompanying Name Books simply as 'a mound', and then, over the following century and more, it was gradually eaten away by gravel quarrying until nothing visible remained. What survives now is the entry in the record, the contour of the hillock, and the memory of the landowner, who recalls a big mound being quarried for many years.

The 1841 Ordnance Survey mapping was part of a remarkable national effort to document Ireland's landscape in exhaustive detail, and the accompanying Name Books, sometimes called the Ordnance Survey Name Books or OSNB, were field notebooks in which surveyors recorded local place names, physical features, and whatever antiquities they encountered. The circular enclosure shown at Ballykevan, around twenty metres in diameter, fits the general profile of a low earthen mound of the kind found across Ireland, though without further investigation its precise nature and date remain unknown. Such mounds can represent anything from prehistoric burial monuments to medieval features associated with landholding or ritual. The compiler of the modern record, Denis Power, noted the site's condition as of 2011, by which point the quarrying had already done its work.

There is, in practical terms, very little to see at Ballykevan today. The site sits in private farmland, and the monument itself no longer presents any visible surface trace. Its interest lies less in what a visitor might observe on the ground and more in what the record reveals about how quickly an earthwork can be lost once it becomes a convenient source of aggregate. The hillock itself presumably remains, since the underlying topography does not quarry away as easily as a built-up mound, and that gentle rise in the pasture is now the only physical suggestion that something once stood there.
