At Ballyegny, a circular earthwork sits on a gentle east-facing slope in pasture, its enclosing bank absorbed so thoroughly into a later field boundary that the two have become almost inseparable. That stepped internal profile is the giveaway: the lower inner section appears to be the original enclosing bank of a rath, with a higher outer section added at some later point when a farmer decided the existing earthwork would do perfectly well as a field division.

A rath, or ringfort, is a roughly circular enclosure defined by one or more earthen banks and ditches, typically built during the early medieval period in Ireland, broadly between the fifth and twelfth centuries, and used as a farmstead or small settlement. This example measures 22.5 metres across both north to south and east to west, making it a modest but clearly defined example of the type. The scarped edge running from north-northeast to south-southwest stands around 0.6 metres high and nearly four metres wide at its base, while the field boundary that curves around from the southwest back to the north-northeast rises to 1.5 metres on the interior and 0.9 metres on the exterior. Compiled by Denis Power and uploaded to the record in August 2011, the site is catalogued in the national monuments database. Notably, a second ringfort sits approximately 40 metres to the southwest, suggesting this was once a more densely settled corner of the parish than its current agricultural appearance implies.

The site lies in pasture and, as with most earthworks of this kind in Limerick, there is no formal visitor access or signage. The east-facing slope means that morning light picks out the subtle changes in ground level most clearly, making that stepped bank profile easier to read from the inside of the enclosure. The interior itself is level and grass-covered. Anyone approaching should do so with permission from the landowner and a willingness to move slowly; the real interest here lies in reading the relationship between the ancient bank and the later field boundary that swallowed it, and that requires pausing long enough to notice the difference in height between the two phases of construction.
