The earthwork, roughly thirty-five metres across when it was recorded, has been levelled entirely, leaving no visible surface trace. What once stood here, a rath, meaning a roughly circular enclosure of raised earthen banks that would have enclosed a farmstead during the early medieval period, is now agricultural land given over to tillage. The site survives only as a mark on an 1842 Ordnance Survey six-inch map, where a neat circular line was carefully inked in by surveyors who could still see something worth recording.

The 1842 survey captured the enclosure at a moment when it was already, presumably, diminished. In the decades and centuries that followed, ploughing gradually did the rest. This was a common fate for Irish ringforts, of which thousands once dotted the countryside; many were removed deliberately, others slowly eroded by agriculture. What makes Ringacoltig mildly curious is the proximity of a second circular enclosure, recorded about a hundred and forty metres to the south-west. Two such sites in close company is not unheard of, but it hints at a locality that was, at some point in the early medieval period, genuinely settled and organised, with families or related groups establishing adjacent enclosures across the same slope.
