Set into a north-facing slope at Liscullane, this ringfort, or rath, sits in ordinary pasture, its circular outline blending into the undulating ground until you notice that the interior has been artificially levelled, raised higher on the northern side to compensate for the natural fall of the hillside. That kind of careful adjustment speaks to serious intent. Whoever built this was not simply heaping up a bank in a convenient spot.

A rath is an earthen enclosure, typically dating from the early medieval period, that would once have enclosed a farmstead and offered its occupants a degree of protection and social definition. This one measures roughly 25.6 metres east to west and 25.1 metres north to south, making it a fairly compact example. Its boundary is formed by a scarp, a pronounced slope of ground rather than a free-standing wall, reaching up to 1.1 metres at its highest point, with faint traces of an internal lip still visible along the south-southwest to west arc. Beyond the scarp runs a shallow external fosse, a defensive ditch, which becomes waterlogged along its northern and eastern stretch. The site was already old enough to be mapped when the Ordnance Survey carried out its six-inch survey of Ireland in 1842, where it appears as a hachured, nearly circular enclosure, the conventional cartographic shorthand for an earthwork of this kind.
