At a location in Camas, County Limerick, a ringfort once occupied a gently south-facing slope in what is now open pasture. No earthwork survives. No bank, no ditch, no shadow in the grass to suggest anything ever stood here at all.

A ringfort, or rath, is one of the most common monument types in the Irish countryside, typically a circular area enclosed by one or more earthen banks and ditches, used as a farmstead during the early medieval period. They number in the tens of thousands across the island. The example at Camas was recorded on the Ordnance Survey six-inch map of 1924, depicted as an embanked circular enclosure with a diameter of approximately 45 metres, a modest but fairly typical size for such a monument. By the time researcher Denis Power inspected the site, compiled for the record in August 2011, nothing remained. The monument had been levelled entirely, leaving no visible trace on the ground.

For anyone inclined to visit out of curiosity or a particular interest in the archaeology of absence, the site sits in agricultural land and there is, practically speaking, nothing to observe on the surface. The 1924 OS map remains the clearest documentary evidence that something was once here. What the levelling involved, and precisely when it happened, is not recorded in the available notes. That gap is itself part of the story: a site catalogued on a map, inspected decades later, and found already gone, with the pasture carrying on as though the enclosure had never interrupted it.
