The Ordnance Survey, diligent recorders of the Irish landscape across successive editions, missed it entirely. It took an aerial camera to find it.

The site is a ring-barrow, a type of prehistoric funerary monument typically consisting of a low central mound enclosed by a circular ditch, known as a fosse, and sometimes an outer bank. This example, recorded in the national monuments register as LI024-064----, was first identified during the Bruff aerial photographic survey in 1986, when the circular form became legible from above as cropmarks or soil variations invisible at ground level. That survey recorded both the outer ring (Bruff 30.1), with its surrounding fosse about two metres wide, and a central mound within the interior (Bruff 30.2). The Archaeological Survey of Ireland followed with its own aerial record on 23 August 2000. Neither historic OSi mapping nor casual ground inspection had flagged the monument beforehand; it is the kind of site that reveals itself only when light and moisture conditions are just right, and an aircraft happens to be overhead. A second ring-barrow lies roughly fifty metres to the north, and an enclosure abuts that monument to the east, suggesting this stretch of Limerick pasture was once a more deliberate ceremonial or burial landscape than its current appearance suggests.

The barrow sits approximately 260 metres south of the Glenatrahaun Stream, near the townland boundary with Ballynagally. In practical terms, the site is in private agricultural land and there is no formal public access. For those with an interest in remote sensing and landscape archaeology, it is worth knowing that the monument remains faintly visible on Google Earth imagery taken as recently as November 2018, particularly under the right seasonal conditions. Wet ground in late autumn or early spring tends to preserve the subtle colour differences that betray buried or semi-buried earthworks from above. Looking at the OSi orthoimages from 2005 to 2012, or the Digital Globe imagery from 2011 to 2013, gives the clearest read of the site's circular outline, the interior space, and the surrounding fosse that cartographers working on foot simply never caught.
