A roughly circular enclosure measuring about 28.5 metres north to south and 30 metres east to west sits on a gentle west-facing slope in County Limerick, its edges defined not by a tall bank but by a scarped edge, a cut or shaved face of ground, rising only about half a metre and extending roughly two and a half metres in width. It is the kind of feature that a casual walker might register as a slight change in the lie of the land and think nothing more of it.

Ringforts, known in Irish as raths when defined primarily by earthworks rather than stone, were the standard form of enclosed farmstead in early medieval Ireland, typically dating from the period between roughly 500 and 1000 AD. Thousands survive across the country in varying states of preservation. The Lisbane example, compiled by Denis Power and uploaded to the record in August 2011, shows some of the accumulated indignities common to such sites. Boulders have been dumped against the scarp at the north and east, obscuring its original profile. The stone-facing that once lined the scarp from the south-southeast around to the north is still visible in places but diminishes as it runs towards the west-northwest. Within the interior, the ground slopes down to the west, and the higher south-east quadrant is separated from the rest by its own internal scarped edge, roughly 0.6 metres high and just over three metres wide, suggesting the enclosure was at some point divided or phased in its use. Mature beech trees now grow along the verges, lending the site a density of shade that is almost certainly not original to it.

The remains of an old farm passageway kink around the outside of the south-west arc, which is a reminder of how often these features have been quietly absorbed into later agricultural landscapes rather than cleared away. The site lies in pasture, so the ground underfoot is likely to be uneven and potentially soft in wetter months. There are no formal access arrangements recorded, and visitors should treat the surrounding farmland with the usual consideration. The internal division and the surviving stone-facing on the scarp are the most instructive details to look for; standing at the higher south-east quadrant gives the clearest sense of how the original enclosure was shaped and oriented.
