A ringfort, or rath, was a circular earthwork enclosure used in early medieval Ireland, typically as a farmstead or defensive residence, defined by one or more earthen banks and ditches. Here, even that modest structure is largely gone, levelled at some point before anyone thought to record it carefully.

The site has been quietly disappearing for a long time. When the Ordnance Survey mapped this part of north Cork in 1842, the enclosure was still legible enough to be drawn as a hachured circle, approximately 25 metres across. By the time the survey was revised in 1937, only a partial arc remained visible, shown as a scarp running east to west. Bowman, writing in 1934, noted it as already levelled, describing a single-ramparted fort of around 33 yards in diameter on land belonging to a J. O'Connor. The surviving arc, curving over roughly 36 metres, is all that now marks where the bank once ran its full circuit. It is the kind of site that asks something of the imagination, the ground itself offering only the faintest echo of what the nineteenth-century mapmakers still recognised clearly enough to draw.
