The hill is known locally as Knockaunnamoughilly, and what makes this site quietly arresting is not just its geometry but its purpose: archaeologists classify the outer enclosure as a possible ritual hilltop enclosure, a type of prehistoric monument associated with ceremony rather than settlement or defence, and the mound at its centre as a possible barrow, the kind of earthen burial mound that was constructed across Ireland during the Bronze Age.

The site appears on the 1840 Ordnance Survey six-inch map, where the inner enclosure is shown sitting within a large circular field of approximately 115 metres in diameter, a field boundary that may itself preserve the outline of the ancient monument. When the Archaeological Survey of Ireland examined it in 1999, surveyors recorded a circular, flat-topped mound whose base is partially enclosed by a fosse, a ditch cut into the ground, running from the east around through the south-east to the south. More recent aerial imagery, including Digital Globe orthophotos taken between 2011 and 2013 and a Google Earth image from June 2018, shows the mound clearly as a tree-covered feature sitting within the outer enclosure, which measures roughly 100 metres east to west and 90 metres north to south. The site record was compiled by Alison McQueen, Vera Rahilly, and Caimin O'Brien, and uploaded in July 2020.

The hill lies in level pasture approximately 125 metres south of the Clare River, and the survey notes that it commands excellent views in all directions, which may partly explain why this particular summit was chosen for a monument of apparent ritual significance. The tree cover on the central mound makes it visible from a distance in an otherwise open landscape. Access to fields of this kind in rural Limerick is typically across farmland, so permission from the landowner would be the sensible first step before approaching on foot. The circular field boundary noted on the 1840 map is worth looking for; it gives a sense of how faithfully the landscape has preserved the original layout across nearly two centuries of recorded mapping, and almost certainly much longer before that.
