The earthwork at Cloonty, in County Limerick, is a roughly circular feature just five metres in diameter, its perimeter formed by a low, broad earthen bank that rises barely forty centimetres from the surrounding ground. That bank is almost as wide as it is tall, giving it a spread of around three metres. What makes the feature stranger still are two wide opposing gaps, one to the north and one to the south, each measuring roughly four and a half metres across. In other words, the entrances are nearly as wide as the enclosure itself, which raises the obvious question of what, precisely, was being enclosed.

The site sits in undulating pasture, the kind of ordinary agricultural landscape that conceals a surprising density of early monuments across the Irish midlands and west. Earthen enclosures of this general type are familiar enough in the Irish archaeological record, ranging from large ringforts, which were typically used as defended farmsteads in the early medieval period, down to much smaller features whose function remains genuinely uncertain. Some may have served as animal pounds, ceremonial spaces, or boundaries associated with burial. At Cloonty, the combination of modest scale and unusually wide opposing entrances does not map neatly onto any single category. The site was recorded and compiled by Denis Power and added to the record in August 2011, suggesting it may have been noted during fieldwork rather than excavation, meaning its interior has not been examined in any systematic way.

The enclosure lies in working farmland, so access would require landowner permission before any visit. Because the bank is low and the surrounding pasture undulating, the feature could easily be overlooked from a distance, and the best conditions for spotting earthworks of this kind tend to be in low winter or early spring light, when the sun sits close to the horizon and casts shadows that reveal subtle changes in ground level. If you do find it, the thing worth pausing over is the geometry: stand at one of those wide gaps and consider how little of the circuit the bank actually completes, and how open the whole structure would have been to anyone approaching from either direction.
