This one is notable, in a quieter way, for what does not. At Ballintredida in County Limerick, a ringfort once occupied a break in a south-facing hill-slope, set among the kind of outcropping limestone that makes much of this part of Munster feel older than it looks. A ringfort, or rath, is a roughly circular enclosure defined by an earthen bank and ditch, the typical farmstead of early medieval Ireland, built to shelter a family and their livestock. The Ballintredida example measured around twenty metres in diameter, modest even by the standards of such monuments. Today, nothing of it survives above ground.

The site was recorded on the Ordnance Survey six-inch map of 1841, where it appears as an embanked circular enclosure, legible enough to be mapped and noted. That survey, conducted in the decades following the Act of Union, captured thousands of such monuments across the Irish countryside, many of which were already under pressure from agricultural improvement and land clearance. At Ballintredida, the process went to completion. By the time Denis Power inspected the site and compiled his record in 2011, the monument had been levelled entirely, the pasture running unbroken across what the nineteenth-century cartographers had carefully drawn. No earthwork, no depression, no scatter of material remained to indicate where the enclosure had stood.

For anyone curious enough to seek it out, the location is in open pasture on a hillside with a southward aspect, in an area where limestone breaks through the surface in the way characteristic of much of County Limerick's interior. Access to farmland of this kind requires landowner permission, and there is nothing visible to reward the effort of the walk. The value of the site lies not in any physical experience of it but in what the archival record preserves: the fact that something was here, that it was mapped, and that its disappearance has itself been documented. The 1841 OS six-inch map remains the most tangible evidence that a settlement of some kind once shaped this small patch of hillside.
