This one offers nothing of the sort. In a pasture on a south-facing slope at Killasseragh in County Cork, a ringfort once stood that is now entirely gone from view, levelled so completely that the grass gives no hint of what lies beneath. A rath, as this type of enclosure is generally known in Ireland, was typically a circular earthwork bank and ditch enclosing a homestead, used predominantly during the early medieval period. Thousands survive across the Irish countryside in varying states of preservation. This one has not survived at all, at least not above ground.

What we know of its shape and position comes from the Ordnance Survey's six-inch map of 1842, which recorded it as a circular area of roughly 35 metres in diameter. Even then it was not fully intact; a field fence running northeast to southwest already clipped its northwestern edge. At some point after that mapping, whatever earthwork remained was levelled entirely, most likely through agricultural improvement or the steady encroachment of field boundaries. The 1842 survey caught it at an intermediate stage, already compromised but still legible enough to be worth marking. Now even that partial outline is gone.
