In a stretch of level pasture in Gortboy, in the barony of Glenquin in County Limerick, there was once a rath, the Irish term for a ringfort, which is a type of enclosed farmstead typically dating from the early medieval period, roughly 500 to 1200 AD. These circular earthworks, defined by one or more banks and ditches, were once so numerous across the Irish countryside that they numbered in the tens of thousands. This one, however, has gone entirely.

When surveyor Denis Power inspected the site, no trace of the monument was evident on the ground. The only evidence that anything was ever there comes from the 1924 Ordnance Survey six-inch map, which depicts a circular enclosure of approximately 40 metres in diameter. At some point between that mapping and the inspection, the earthwork was levelled, most likely through agricultural improvement, the gradual smoothing and reseeding of pastureland that claimed so many similar monuments across Limerick and the wider country during the twentieth century. The record was uploaded in August 2011.

For anyone visiting this part of County Limerick, Gortboy offers nothing in the way of visible archaeology. The land is flat and open, and the field gives no indication of what it once contained. That said, there is a particular kind of interest in coming to a site like this, knowing that the map and the monument record together preserve the outline of something that the ground itself no longer shows. If you want to locate the approximate spot, the 1924 OS six-inch map sheet is the most useful reference, and cross-referencing it with the current landscape is a small exercise in reading absence. The site is a reminder that the historical record and the physical landscape do not always agree, and that the gap between them is itself worth noting.
