Not obscured by trees or overgrowth, not flooded or built over, simply gone below the threshold of visibility, dissolving into the pasture around it until the ground itself gives nothing away. What was once confident enough to be marked on the 1837 Ordnance Survey six-inch map as a circular enclosure warranting the label "Fort" has, in the intervening century and a half, retreated almost entirely from view.

When investigators examined the site in 1987, what they found was marginal: a slightly raised circular area roughly thirty metres in diameter, ringed by very fragmentary traces of a low bank of earth and stone. There was no fosse, the defensive ditch that typically surrounds an earthen ringfort, and no recognisable entrance. Stone protruded from the interior, suggesting something once more substantial lay beneath the soil, but the structure as a whole was not visible at ground level. Ringforts, which date broadly from the early medieval period and served as enclosed farmsteads or settlement sites, survive in their thousands across Ireland, and their earthworks can endure for well over a millennium. That this one has declined to near-invisibility within a working agricultural landscape is itself part of what makes it worth noting. The 1837 map marks what the cartographers could still see or what local knowledge still confirmed; a century and a half of pasture management quietly did the rest.
