In Tomdeely North, County Limerick, a ringfort that once sat on a gentle rise above low-lying pasture has been so thoroughly erased that when the site was inspected, no trace of it remained at all. In its place stand a barn and a farm shed, recently built, occupying the ground where an enclosure roughly twenty-five metres across once defined the boundary of an early medieval farmstead.

Ringforts, known also as raths, were the most common settlement type in early medieval Ireland, typically consisting of a circular area enclosed by one or more earthen banks and ditches. They served as farmsteads for families of varying social rank, and tens of thousands were once scattered across the Irish landscape. The Tomdeely North example is recorded on the 1841 Ordnance Survey six-inch map, depicted as an embanked circular enclosure, which means it was still sufficiently intact in the mid-nineteenth century to be carefully noted by the surveyors. At some point between that survey and the inspection recorded by Denis Power in 2011, the monument was levelled entirely. The slight rise on which it sat, a topographical detail that would have made the enclosure visible from some distance across the flat surrounding land, still exists in theory, but the earthworks themselves are gone.

The site lies in agricultural land in north County Limerick, and there is frankly little to see on the ground today. The value of knowing about it lies less in any prospect of a visit and more in what the record itself represents: a monument that survived from early medieval times into the age of cartography, was mapped and catalogued, and was then lost within living memory. Anyone with an interest in the Ordnance Survey's early mapping work might compare the 1841 six-inch sheet with the current landscape as a way of reading what has changed. The barn and shed that now occupy the site are ordinary agricultural structures with no heritage significance, but they mark a location worth knowing about, even if only on paper.
