This is a rath, the Irish term for a ringfort, the most common type of early medieval settlement monument in the country. Thousands were built across Ireland, typically between the sixth and tenth centuries, as enclosed farmsteads for a single family and their livestock. Most are modest in scale, and this one is no exception, measuring roughly 35 metres in diameter.

The enclosure is formed by an earthen bank standing about 0.8 metres high on its north-western to western arc, with an external fosse, essentially a ditch, cut to a depth of around 0.7 metres running outside it. A causeway crosses this fosse to the west, marking what would have been the original entrance point. The fosse is itself now bounded by a field boundary, meaning the ringfort has been quietly absorbed into the working landscape around it over the centuries. More intriguing still is the presence of a souterrain in the interior. A souterrain is an underground stone-lined passage or chamber, typically associated with ringforts and thought to have served as storage space, a refuge, or both. Their construction required considerable effort, which suggests the people who lived here had something worth protecting or preserving.
