The enclosure at Cappanahanagh survives as a low oval mound on a gentle knoll, its northern portion long since levelled and absorbed into the surrounding field boundaries. What you are looking at, in other words, is an archaeological site that has been edited by farming over the centuries, and what you are left with is a partial ghost of a structure that was once clearly defined enough to be mapped.

The earliest cartographic record of the site comes from the 1840 edition of the Ordnance Survey six-inch map, which shows it as a circular enclosure. By the time the more detailed OS 25-inch map was produced in 1897, the northern half had already been incorporated into field boundaries, suggesting the damage occurred sometime in the intervening decades. The enclosure itself is oval, measuring approximately 27 metres northwest to southeast and 22 metres northeast to southwest. It sits on the southwestern side of a pond occupying a glacial hollow, a landscape feature formed during the retreat of ice sheets, and from the knoll there are views across towards Limerick City. The broader area is notably rich in related monuments: a holy well annotated as Toberaguile lies 180 metres to the southwest, a possible hilltop enclosure or royal fort associated with Lisgorey sits 850 metres to the north, and a smaller ringfort, the circular earthwork farmsteads common across early medieval Ireland, lies 500 metres to the north-northeast. Whether the Cappanahanagh enclosure belongs to the same broad tradition of settlement or served a different function is not recorded. The site was compiled by Edmond O'Donovan and uploaded to the record in July 2020.

The earthwork is not obviously dramatic on the ground. It registers as a low relief feature, the kind of subtle rise that is easy to walk past without recognition. Aerial imagery has been more revealing: Digital Globe orthophotos taken between 2011 and 2013 show the earthwork in relief, and a Google Earth image from 28 June 2018 captures it as a cropmark, where the buried structure influences how vegetation grows above it, producing a faint but legible outline from above. The site lies on private farmland in the townland of Cappanahanagh, southwest of Boarmanshill, and any visit would require landowner permission. The cropmark evidence suggests summer, when differential growth is most visible, as the most useful time to observe aerial imagery of the site.
