The early Ordnance Survey cartographers who produced the 1840 six-inch map recorded this site as 'Lisnamoyle', annotating it as an embanked fort, and in doing so preserved an identity that the land itself has largely forgotten. Today the earthworks are poorly preserved, their outlines softened by centuries of agriculture and weather, yet they remain legible enough to reward anyone paying close attention.

Ringforts, sometimes called raths, were the most common form of rural settlement in early medieval Ireland, typically consisting of a circular area enclosed by one or more earthen banks and ditches, used as a farmstead and enclosure for livestock. This one, located around 560 metres south-west of the townland boundary with Carrigeen, was recorded on the 1897 edition of the Ordnance Survey 25-inch map with external dimensions of roughly 52 metres north to south and 45 metres east to west. An entrance, approximately 7 metres wide, was noted on the south-east side. Later aerial analysis, including Google Earth orthoimages captured in 2009, 2015, and 2020, has helped clarify the site's structure. An image from April 2015 in particular suggests that the central enclosure is surrounded by a bank, a fosse (that is, a defensive ditch), and a further external bank, a layout typical of more substantial ringfort constructions. The interior dimensions, as visible on more recent orthoimages, measure approximately 43 metres north to south and 34 metres east to west. The site sits around 700 metres north-west of a separate large enclosure recorded elsewhere in the area.

Visitors approaching on foot should expect an unremarkable agricultural landscape that gives little away from a distance. The monument is not signposted and access depends on the usual courtesies of approaching farmland. The earthworks are best appreciated from elevated vantage points or through aerial imagery rather than at ground level, where the banks can appear as little more than gentle rises in the pasture. The OSi historical map viewer allows anyone to overlay the 1840 and 1897 survey editions onto the modern landscape, which is perhaps the most useful tool for understanding what once stood here and how the name Lisnamoyle attached itself to this particular corner of Limerick for long enough to be written down.
