It came to light through an aerial photograph, part of the Bruff Survey, where the subtle geometry of its earthworks became legible from above in a way that would be almost invisible at ground level. That is part of what makes it quietly arresting: a monument that reveals itself most clearly from the sky, and that has sat in ordinary pasture, on a north-west-facing slope in County Limerick, without any particular fanfare.

The enclosure is sub-rectangular in plan, measuring roughly 32 metres on its north-north-east to south-south-west axis and 18 metres across. Its edges are defined by a combination of scarped ground and an earthen bank, the scarping being most pronounced on the downslope, west-north-west side, where it reaches 0.8 metres in height. A scarped edge, in this context, simply means the ground has been cut or worn away to create a defined drop, effectively marking the boundary of the enclosed space. There is an opening in the bank at the west-south-west, and an external fosse, a shallow ditch, runs along the north-north-west to south-west side. Inside, a further linear scarp crosses the interior, creating a lower level in the south-west sector. A dry water channel feeds into the fosse from the south, and a large dry stream bed runs immediately to the west, suggesting the surrounding drainage has changed considerably over time. A ring-barrow, a type of low circular burial mound, lies approximately 150 metres to the west-north-west, which may be significant. According to archaeologist Doody, writing in 2008, the overall shape and construction of this enclosure point towards a possible Bronze Age date, placing it somewhere in the broad period between roughly 2500 and 500 BC.

The monument sits in pasture and was compiled by Denis Power, with the record uploaded in November 2013. Because it was identified primarily through aerial survey rather than ground investigation, its features are subtle, and a visitor should not expect dramatic earthworks. The most legible element on the ground is likely the downslope scarping on the western side. The nearby ring-barrow, catalogued separately, is worth locating as a point of comparison, and together the two sites hint at a small cluster of prehistoric activity in this corner of south County Limerick.
