The one recorded at Ballykissane in County Kerry takes a quieter form: it has been levelled almost entirely, and only the faintest traces of its enclosing bank remain to suggest where it once stood. A ringfort, or rath, was a roughly circular enclosure built during the early medieval period, typically serving as a defended farmstead for a single family. This particular example, known in Irish as Liosán an Phortaig and recorded under the anglicised form Lissaunaporty, would have had an internal diameter of around thirty metres, placing it on the smaller end of the scale for such monuments.

The site appears on both the first and second editions of the Ordnance Survey maps, though the two surveys recorded its outline differently: the earlier edition shows it as an oval, while the later one depicts a circle. That discrepancy is a small puzzle in itself, possibly reflecting the difficulty of reading a heavily degraded earthwork on the ground. By the time archaeological survey work was carried out on the Iveragh Peninsula in the 1990s, the enclosure had been reduced to those faint surface traces, the bank no longer rising in any meaningful way above the surrounding land. What survives is more a matter of subtle difference in ground level than any visible structure.
