The most northerly of the three, it sits in the south-western corner of a grassland field, partially overwritten by field boundaries that were drawn up after 1700, cutting across the monument at its south-western, south-eastern, and southern edges. The fact that those later boundaries had to accommodate, however imperfectly, a structure that was already ancient says something about how stubbornly these earthworks persist in the landscape.

A ringfort, or rath, is a roughly circular enclosure defined by one or more earthen banks and ditches, typically associated with early medieval settlement and farming in Ireland, often serving as a defended farmstead. This example was already being recorded cartographically by the time the Ordnance Survey produced its six-inch map in 1838, which noted a sub-circular bank defining the enclosure. By the 1897 twenty-five-inch survey, the dimensions had been captured with greater precision: an interior diameter of approximately 28 metres north to south and 24 metres east to west, with an external diameter of around 42 metres, enclosed by a bank running from the north-east through the south to the west, and a scarp from the north-west to the north-east. Its two companion ringforts lie 63 metres and 190 metres to the south-east respectively, the three together spanning roughly 200 metres along a north-west to south-east axis. What prompted their alignment, and whether they were contemporary or accumulated over generations, is not recorded in the available evidence.

More recent aerial and satellite imagery has continued to reveal detail that ground-level visits might miss. Digital Globe imagery from 2011 to 2013 shows a tree-covered enclosing bank with a gap at the north-north-west, while a Google Earth orthophoto from November 2010 picks up traces of an outer ditch running from the south through to the north-west, though these may relate to post-1700 drainage activity rather than the original monument. The outline remained legible in imagery from November 2019. For anyone visiting the area, the site sits in open grassland and the tree-covered bank provides the clearest visual indicator of the enclosure; later field boundaries will complicate any reading of the perimeter, so it is worth consulting the mapped survey data compiled by Fiona Rooney and Martin Fitzpatrick before approaching.
