The 1897 edition of the OSi 25-inch map shows a subrectangular-shaped parcel of ground in Garrane More, County Limerick, with no indication that anything of archaeological note lay beneath the grass. The 1840 edition does not mention it at all. Yet what sits in this patch of wet pasture, on a gentle north-facing slope beside a small watercourse and close to the townland boundary with Moymore, is almost certainly an ancient enclosure, the kind of earthwork that defined settlement, territory, or ritual space across Ireland for millennia, and that has spent the better part of two centuries being quietly mistaken for an ordinary farm boundary.

A brief note by O’Dwyer in 1959 described the feature as a ‘low platform’, which is perhaps the most honest first impression: the ground simply rises, almost imperceptibly, before you understand what you are looking at. When the Archaeological Survey of Ireland examined it properly in 2008, the picture became considerably clearer. The monument is a raised subrectangular area measuring roughly 51 metres on its NNE-SSW axis and 32 metres ESE-WNW, defined along much of its western, northern, and eastern sides by a scarp, a low step in the ground formed by the edge of the raised platform, ranging between one and nearly two metres in height. Outside that scarp, on the same three sides, runs an outer fosse, a shallow ditch, roughly four metres wide and less than half a metre deep, which would once have reinforced the enclosure’s boundary more visibly. Perhaps most intriguing is a smaller circular raised area, about ten metres in diameter, visible within the south-eastern quadrant of the enclosure. Its function is unclear, but its presence suggests the interior was not simply an open yard. Modern interventions have complicated the picture: a concrete wall cuts through the eastern side, a linear drain interrupts the fosse to the west, and a public road bisects the southern end entirely.

The enclosure is situated in farmland and is not a managed visitor site, so access is a matter of courtesy and practicality. The monument is most legible from aerial imagery, and the Archaeological Survey of Ireland’s 2008 sketch plan, compiled by Alison McQueen and Vera Rahilly, remains the clearest guide to what survives on the ground. Visitors approaching on foot should be prepared for wet underfoot conditions, particularly in the northern half of the field where the slope channels water toward the adjacent watercourse. The scarp is subtle but present, and once the eye adjusts to the slight rise of the platform, the overall shape of the enclosure becomes easier to read. The circular feature in the south-east quadrant, partly cut away by the concrete wall, requires more careful attention and is best appreciated with the 2008 plan to hand.
