A rath, as ringforts are commonly known in Irish placename tradition, is an enclosed farmstead of early medieval date, typically defined by one or more earthen banks and ditches thrown up around a dwelling and its immediate yard. This particular example near Sallymount measures roughly 25 metres in diameter, though that figure comes from cartographic inference rather than from any intact physical boundary you could walk around today.

The record compiled by Edmond O'Donovan draws entirely on maps and aerial photographic evidence, which is itself telling. The earlier Ordnance Survey mapping shows a recognisably circular enclosure with a lime kiln, a small industrial furnace used for burning limestone to produce agricultural lime, built into the eastern face of the bank. By the time the 1897 25-inch OS map was produced, the site had already been partially quarried away, its neat circularity broken into an irregular earthwork. The quarrying was almost certainly connected to the lime kiln itself; the bank may have been mined as a convenient source of limestone to feed the furnace. Over subsequent decades, farm development finished what quarrying had started, and modern agricultural buildings now occupy the footprint where the enclosure once stood. A curving fragment of bank to the north was still visible on Digital Globe orthophotographs taken between 2011 and 2013, though whether that trace remains clear on the ground is another matter.

The site sits on gently undulating pasture immediately east of a historic farmyard, and because it is now largely built over, there is little to see without access to aerial imagery. Anyone with a serious interest would do better to begin with the relevant OS map layers or satellite views online, where the residual curve of the northern bank can at least be traced against the modern farm layout. This is, in the end, a site that repays attention paid at a screen rather than in the field, a reminder that a great many Irish ringforts survive in the record rather than in the landscape.
