It was only spotted from the air. That particular oversight, repeated across generations of cartographers, is itself a kind of small puzzle, given that a ring-barrow of this scale is not easily overlooked once you know what to look for.

A ring-barrow is a circular burial monument of the Bronze Age or Iron Age, typically consisting of a low central mound enclosed by a ditch, or fosse, sometimes with an outer bank. The fosse is what gives the feature its visibility in aerial and satellite imagery, where the circular cropmark or shadow reads clearly against surrounding pasture. This example, catalogued as Bruff 202 during a 1986 aerial photographic survey of the Bruff area, sits on a north-facing slope in Cahercorney, overlooking the Camoge River some 330 metres to the north. It lies approximately 250 metres north-east of a standing stone already recorded in the Sites and Monuments Record. The proximity of the two monuments suggests this corner of south County Limerick had some significance in prehistoric times, though the nature of any relationship between them is unknown. The barrow was compiled into the record by Edmond O'Donovan and uploaded in August 2020, meaning its formal documentation is relatively recent despite the aerial identification dating back nearly four decades.

The monument sits in working farmland and is not publicly accessible in any formal sense. It is bounded closely by field boundaries, with the northern edge of the barrow coming within 3 metres of an east-west field wall and the eastern edge within 7 metres of a north-east to south-west boundary. Those who want to get a sense of its scale and form without trespassing can examine it through Google Earth, where orthoimages from April 2006 and June 2018 both show the circular feature clearly in the pasture. The standing stone to the south-west, if accessible, might offer a reasonable vantage point from which to appreciate the broader landscape in which both monuments sit, sloping gently down towards the Camoge.
