It is a rath, the Irish term for a ringfort, and the fact that it has survived at all in usable farmland says something about how durable these structures can be, even when reduced to a modest rise in the ground.

The enclosure measures roughly 23 metres north to south and 22.5 metres east to west, making it a fairly typical example of the smaller end of the ringfort spectrum. A bank of earth and stone, standing only about 0.65 metres high along the western to south-eastern arc, defines the boundary on that side; elsewhere the perimeter takes the form of a scarp, a sharp natural or cut slope, rising to around 1.2 metres and faced with stone in places. Ringforts are the most common archaeological monument type in Ireland, built predominantly during the early medieval period, roughly the fifth to the twelfth centuries, and used as enclosed farmsteads by farming families of varying status. What makes this one quietly interesting is the possible presence of a souterrain in its interior. A souterrain is an underground stone-lined passage or chamber, often associated with ringforts and interpreted variously as a place of refuge, cold storage, or both. The qualification "possible" matters here; the feature has been recorded but not excavated, so its full extent and purpose remain open questions.
