For most of the Victorian era, it simply went unnoticed, or at least undocumented, despite being a raised, scarp-defined ring roughly 31 metres across. That omission is telling. The Ordnance Survey's first major Irish mapping effort, the six-inch series of 1840, passed it by entirely. It only surfaces in the cartographic record on the 25-inch edition published nearly six decades later, annotated as a raised circular area defined by a scarp, which is an abrupt change in ground level forming a natural or constructed edge.

The site sits at the southern edge of a large upland forestry plantation, approximately 120 metres west of the Coolbaun River, and a related enclosure, a separate but likely connected monument, lies around 115 metres to the south-east. The earthwork itself is classified under the reference LI049-165---- in the national record of monuments. Its origins and precise function have not been established in the available survey notes, compiled by Martin Fitzpatrick and uploaded in October 2021, and the site has not been excavated or formally interpreted beyond its physical description. What is known comes largely from map regression and aerial imagery: a Digital Globe orthoimage taken between 2011 and 2013 shows the circular form still clearly legible, defined now by the line of trees growing along its edges, and Google Earth imagery confirms scrub has taken firm hold across the monument itself.

Accessing the site is not straightforward. It lies within or immediately adjacent to upland plantation forestry, which tends to mean dense, unmanaged ground cover and few obvious paths. The Coolbaun River provides a useful orientation point to the east. Anyone hoping to view the earthwork with any clarity may find satellite or aerial imagery more revealing than a ground visit, given the scrub coverage reported across the monument. The related enclosure to the south-east is worth factoring into any visit, since the two monuments in proximity suggest this patch of upland Limerick repays closer attention than its present obscurity might suggest.
