It has no formal monument marker, no interpretive panel, and for most of the year no visible trace at ground level. What it does have is a shape, roughly D-shaped, approximately 25 metres north to south and 24 metres east to west, with a notably straight eastern side running about 28 metres. That straight edge is the kind of detail that catches an archaeologist's eye, suggesting something deliberate rather than a natural feature, and it places this modest earthwork in the broad category of enclosed settlements that dot the Irish landscape, though its precise date and function remain unestablished.

The site came to light not through excavation or ground survey but through aerial reconnaissance. A photographic survey carried out from Bruff in 1986 identified it as a possible enclosure, recorded in the survey records as Bruff 34, reference AP 5/2063. At the time, cropmarks were the main evidence, and cropmarks are among the quieter forms of archaeological visibility: differential growth in cereal or grass crops above buried features can betray the outline of a ditch or bank that has otherwise been ploughed or grazed into invisibility. Later orthophotography taken by Ordnance Survey Ireland between 2005 and 2012 showed a faint cropmark visible from the west, north, and north-east. It was a Google Earth image dated 16 March 2016 that gave the clearest view, with the D-shaped outline showing with enough definition to confirm the dimensions and that straight eastern side. The record was compiled by Martin Fitzpatrick and uploaded in May 2021. About 550 metres to the west lies a hillfort, a larger type of enclosed monument typically occupying elevated ground, which suggests this part of Limerick was a focus of activity at some point in prehistory or the early medieval period.

The earthwork sits roughly 200 metres east of the townland boundary with Rathcannon, in what is now ordinary agricultural land. There is nothing to see from a roadside verge in most conditions, and access to the field itself would require the landowner's permission. The best chance of glimpsing anything is through aerial imagery during a dry summer, when soil moisture differences above buried features produce the cropmarks that first revealed it. For anyone researching the area, the Bruff aerial photographs held in the survey archive and the Google Earth orthoimage from March 2016 remain the most useful sources for understanding what is, in physical terms, a nearly invisible place.
