Most examples across Ireland appear on Ordnance Survey maps going back generations. This one, sitting in low-lying pasture roughly 390 metres south-west of an inlet of the Shannon Estuary in County Limerick, does not. It escaped the cartographers entirely, appearing on no OS historic mapping, which makes its existence feel all the more quietly anomalous.

The cairn was identified in 1999 by Celie O'Rahilly, not through any formal archaeological survey, but while walking the route of a proposed ESB power line. That kind of accidental discovery is not unusual in Irish archaeology, though it does sharpen the sense that the landscape still holds things the official record has missed. The mound is large and oval in shape, orientated north to south, and covered in scrub vegetation that has helped obscure it over time. Approximately 22 metres to the south-east lies a second similar feature, suggesting this may not be an isolated monument but part of a small cluster. The site was later visible on Digital Globe orthophotos taken between 2011 and 2013, and on Google Earth imagery from March 2012, where it shows as a roughly oval scrub-covered area measuring around 25 metres on its north-east to south-west axis and 13.5 metres across. The record was compiled by Alison McQueen and Vera Rahilly and uploaded in July 2020.

Accessing the site requires crossing private farmland, so permission from the landowner would be necessary before attempting a visit. The low-lying, estuarine setting means the ground can be soft underfoot, particularly in wetter months, and the scrub covering the mound makes its edges difficult to read at ground level. Viewing the orthoimagery beforehand gives a clearer sense of the oval outline than anything you are likely to perceive on foot. The second feature to the south-east is worth seeking out alongside the first, since together they raise questions about the original purpose and date of these monuments that have not yet been answered.
