The ringfort at Coolballyshane, County Limerick, offers none of these things, and therein lies its peculiar interest. It is, in the most literal sense, a monument to absence.

Ringforts, known in Irish as raths, were enclosed farmsteads typical of the early medieval period, roughly the fifth to twelfth centuries. They generally consist of an earthen bank and ditch forming a circular boundary, inside which a family would have kept their dwelling and livestock. They are among the most common field monuments in Ireland, numbering in the tens of thousands, and their survival in the landscape is usually attributed to a mixture of superstition and the practical awkwardness of ploughing a circle. The Coolballyshane example was recorded on the Ordnance Survey six-inch map of 1923 as an embanked circular enclosure of approximately thirty metres in diameter, sitting on a gently west-facing slope in what is now pasture land. By the time Denis Power inspected it for the record compiled in August 2011, it had been levelled entirely. No trace of the monument was evident on the ground.

For anyone drawn to the site, the address is straightforward enough to locate on modern mapping, though what you will find on arrival is simply a field. The slight west-facing slope is there, and the pasture is there, but the enclosure that once gave the place its classification has gone, graded back into the surrounding land at some point between the 1923 survey and the present day. There is something quietly instructive about standing in a field where a monument used to be recorded, trying to read a landscape that has deliberately, or carelessly, been made unreadable. The Coolballyshane rath is less a site to visit than a category of loss to consider.
