The monument in question is a ring-barrow, a type of prehistoric burial monument typically consisting of a low earthen mound enclosed by a circular ditch and outer bank, and it only came to official notice in 1986, when an aerial photographic survey operating out of Bruff captured its outline from the air.

The survey, logged as Bruff 122.02 and AP 5/2028, identified the feature as one of as many as eight possible barrows concentrated within a single large field in the western part of the townland, an area measuring roughly 125 metres north to south and 175 metres east to west. That density is itself notable; finding even one such monument in improved agricultural pasture is relatively unusual, and a cluster of eight within the same enclosure suggests the area held some sustained significance in prehistory. The site sits approximately 200 metres west of a watercourse that forms the boundary between Garrydoolis and the neighbouring townland of Knockaundoolis. It was subsequently visible as a circular cropmark on Ordnance Survey Ireland orthophotography taken between 2005 and 2012. A cropmark forms when buried features affect the growth of surface vegetation above them, making ancient boundaries and structures legible to a camera at altitude even when invisible at ground level. Notably, the monument does not appear on Google Earth orthoimages, which points to how much the visibility of such features depends on the season, the crop, and the particular conditions of the year the photograph was taken.

The barrow lies in what is now improved pasture, meaning the land has been drained, reseeded, and managed for grazing, which limits what is visible on foot. A visitor should not expect an obvious earthwork mound; without the right lighting or a dry summer revealing differential grass growth, there may be little to see on the surface at all. The field is in the western part of Garrydoolis townland, close to the boundary with Knockaundoolis, and the surrounding landscape is quiet, agricultural County Limerick with no formal access or signage in place. The record was compiled by Martin Fitzpatrick and uploaded in April 2021 as part of ongoing efforts to document monuments of this kind that exist in the landscape without any formal heritage marker to acknowledge them.
