It was only when an aerial photographic survey flew over the area in 1986 that the site was formally identified, its shape emerging from above as a pattern of undulating ground that ground-level inspection would easily overlook. That kind of invisibility is itself telling: many of Ireland's older enclosures survive not as dramatic earthworks but as subtle irregularities in fields that have been grazed and farmed across for centuries.

The survey that caught it, the Bruff aerial photographic survey of 1986, logged the site as Bruff 260 and recorded external dimensions of approximately 27 metres north to south and 33 metres east to west, placing it broadly in the range of a small ringfort or enclosure of early medieval type. A ringfort, to use the common term, is typically a circular or oval area defined by one or more earthen banks and ditches, used in early medieval Ireland as a farmstead or place of settlement. What the Bruff survey could not resolve was the enclosure's precise date or function, and no subsequent excavation appears to have changed that. The undulating ground remained visible on a Google Earth orthoimage taken as recently as June 2018, confirming the site's survival into the present. The record was compiled by Edmond O'Donovan and uploaded to the sites and monuments database in September 2020.

The enclosure sits on the crest of a roughly east-west ridge, with the Camoge River running parallel approximately 300 metres to the south-west. The position gives clear views in all directions, a characteristic shared with two other recorded monuments nearby: a ringfort and cashel on the summit of Knockcorragh, around 430 metres to the east-north-east, and a mound on the summit of Knockateehaun, about 330 metres to the north-west. A cashel is the stone-walled equivalent of an earthen ringfort, and the cluster of such features across these low ridges suggests the landscape was actively organised and occupied during the early medieval period. On the ground, the site lies in pasture and there is nothing dramatic to see, but for anyone moving through this part of Co. Limerick with an eye on the terrain, the gentle swell of the ridge and its relationship to neighbouring monuments makes the topography worth reading carefully.
