Most early Irish enclosures settle for a single earthen bank and perhaps a ditch. Here, on a south-facing break in a Limerick hillside, there are two concentric banks with a fosse between them, a fosse being the formal term for the flat-bottomed or V-cut ditch that typically accompanied defensive or boundary earthworks. The arrangement is not enormous, the interior measuring roughly 25.5 metres north to south and 20 metres east to west, but the investment in its construction suggests the space it enclosed once mattered considerably to whoever built it.

The site was recorded and compiled by Denis Power, with notes uploaded in August 2011. The inner bank survives well enough on its north-east to south-east arc, rising to about two metres on its exterior face, which is a reasonable height for an earthen bank that has been quietly degrading under agricultural use for centuries. Along the northern and eastern sides it runs in a noticeably straight line before curving more gently around from the south-east to the north-west corner, giving the enclosure its sub-rectangular rather than neatly circular plan. The outer bank is lower, reaching only around 45 centimetres above the surrounding ground on its outer face, and it survives only on the southern to west-south-west arc. A linear bank that once ran along the outer edge of the fosse on the south-east to southern side has since been removed, a common enough casualty of field improvement and farm machinery over the past two centuries. The fosse itself, roughly 1.45 metres deep and just under two metres wide, is best preserved at the south-west, where it is scattered with loose stone.

The enclosure sits in pasture and is still actively farmed land, so any visit requires permission from the landowner in advance. A raised farm passage runs close to the western side and provides the most obvious approach point. Once inside, or at the perimeter, it is worth looking at how the interior dips gently toward its own centre, a subtle topography that is easy to miss from a distance. Mature deciduous trees grow along the verges at the north-east and along the southern to west-north-west edge, framing the space in a way that feels older than casual planting. The south-west corner, where the fosse retains its depth and the loose stone has not been cleared, gives the clearest sense of the original structure's ambition.
