A rath, the Irish term for a ringfort, a roughly circular earthen enclosure used as a farmstead during the early medieval period, once sat in pasture here above a sharp fall of ground down to a small stream on the eastern side. It has been entirely levelled, leaving no visible surface trace. The place holds no ruin, no wall, no earthwork. What it holds instead is a paper trail of its own disappearance.

The earliest cartographic evidence comes from the 1842 Ordnance Survey six-inch map, which shows a hachured circular enclosure roughly twenty-five metres in diameter, the standard surveying convention for a raised or banked feature. By the time the same area was mapped in 1904 and again in 1936, that clear circle had been reduced to a semicircular curve running south to north along a field fence, the fort's outline absorbed into a boundary line and little else. A note by Broker in 1937 records that on land belonging to a Cornelius O'Sullivan there was a fort of approximately a quarter of an acre, which aligns closely with the earlier mapped dimensions. Between the mid-nineteenth century and the mid-twentieth, the enclosure was progressively erased, its banks presumably cleared for pasture. The sequence of maps catches that erasure in stages, like a slow exposure.
