Measuring roughly 17 metres north to south and 15 metres east to west, this modest earthwork is defined by a scarp, a sharp change in ground level marking its edge, and it takes a trained eye, or the right aerial photograph, to appreciate what you are looking at. It is the kind of feature that the land has almost swallowed whole.

What makes this particular earthwork historically awkward is its near-absence from the documentary record. The 1837 edition of the Ordnance Survey six-inch map, which captured countless earthworks, enclosures, and field monuments across Ireland during its meticulous survey campaign of the early nineteenth century, makes no mention of it at all. The feature does appear on the later Ordnance Survey 25-inch map, depicted as that raised circular platform. Whether the surveyors of 1837 missed it, or whether it had not yet been identified or cleared enough to be visible, is not clear from the available record. What the modern record does show is an outline still detectable on an orthoimage taken between 2005 and 2012, and a faint circular cropmark visible on a Google Earth image dated 19 September 2019. Cropmarks form when buried or earthwork features affect how vegetation grows above them, leaving subtle variations in colour or height that only aerial photography reliably reveals. The earthwork does not stand alone in this part of Limerick; Knocklong fort, a separate and recorded monument, lies just 120 metres to the south-east.

The site sits immediately north of a watercourse, with a railway track running about 350 metres to the north, which provides a rough orientation for anyone trying to locate it on a map. Access would be across private agricultural land, so permission from the landowner would be necessary before any visit. On the ground, the scarp defining the platform edge is the main thing to look for, though expectations should be modest; this is a subtle feature, and the cropmark that makes it legible in aerial imagery will not be visible from field level. Late summer, when crop and grass growth can emphasise such marks from above, is the season when aerial observers tend to have the best chance of picking them out.
