This one earns it by not surviving at all. What was once a rath, a type of circular earthen enclosure used as a farmstead and defended residence during the early medieval period in Ireland, has been so thoroughly erased from the landscape of Ballaghbehy North that when inspectors came to record it, there was simply nothing left to see.

The evidence that anything ever stood here comes almost entirely from cartography rather than the ground itself. The 1841 Ordnance Survey six-inch map, one of the most detailed surveys of the Irish countryside ever undertaken, clearly depicts an embanked circular enclosure roughly twenty-five metres in diameter on a south-facing slope in rough grazing land. That kind of detail on an OS map is generally reliable; the surveyors of that era were meticulous about marking earthworks, ringforts, and other field monuments even when landowners had little interest in preserving them. At some point between that survey and the inspection compiled by Denis Power and uploaded in August 2011, the monument was levelled entirely. Whether it was cleared for agriculture, eroded gradually, or deliberately removed is not recorded in the notes.

There is, in a sense, nothing to visit here, which is itself the point. The site sits on a south-facing slope in rough grazing land in County Limerick, and without the OS map as a reference, nothing on the ground would suggest that a structure of any kind once occupied the spot. For those interested in landscape archaeology, that absence can carry its own interest; the outline on the 1841 map gives you the approximate location and scale to orient yourself against the present-day terrain, and the contrast between what was documented then and what remains now is a quiet illustration of how quickly even substantial earthworks can vanish. Anyone visiting would need a copy of the historical map for comparison, and should expect nothing more than a grassy slope.
