The earthwork at Kilgarriff survives not as an upstanding monument but as a cropmark, a faint circular shadow pressed into the pasture that only becomes properly visible from above, in satellite imagery. Ringforts, sometimes called raths, were enclosed farmsteads typically dating from the early medieval period, their circular banks and ditches originally defining a household's living and working space. This one has been levelled to the point where a walker crossing the field would likely notice nothing at all.

The site sits in pasture roughly 75 metres south of a hilltop that rises to 176 metres, and its outline, approximately 19 metres in diameter, was already recorded as a circular enclosure on the Ordnance Survey six-inch map of 1840. By the time the 25-inch edition was published in 1897, the surviving feature was described as a roughly circular area enclosed by a bank, suggesting the earthwork was still at least partially visible to surveyors on the ground at that point. Sometime in the intervening century, it was levelled entirely. A second possible ringfort, recorded separately in the Sites and Monuments Record as LI057-027, lies around 95 metres to the north-east, hinting that this part of the hillside once supported more than one early medieval farmstead in relatively close proximity. The site was compiled for the record by Martin Fitzpatrick and uploaded in November 2021.

Because the monument is effectively invisible at ground level, a visit here is less about standing inside an ancient enclosure and more about understanding how much of Ireland's early medieval landscape has quietly disappeared into agricultural land. Digital Globe orthoimages taken between 2011 and 2013, along with Google Earth imagery, show the circular cropmark clearly in certain light and seasonal conditions, typically when differential moisture or soil composition causes the grass above the disturbed ground to grow or colour slightly differently from the surrounding pasture. The field is privately owned working land, so any visit would require landowner permission. Those with an interest in remote sensing or landscape archaeology may find the site more rewarding to examine through the satellite record than in person.
