Ringforts, sometimes called raths, were enclosed farmsteads of the early medieval period, typically defended by one or more earthen banks and a surrounding ditch. What makes this one at Coolcappagh quietly worth attention is the degree to which its structure remains legible despite generations of farm use pressing in on all sides.

The enclosure measures 32 metres across in both directions, a tidy circular form contained by an earth-and-stone bank that still stands to an internal height of around 1.05 metres and an external height of 2.4 metres, the difference reflecting the depth of the fosse, the external ditch dug to reinforce the bank's defensive effect. Traces of internal stone facing survive at the western and east-north-eastern sections, suggesting the bank was once more carefully finished than its current condition implies. There are two gaps: one to the north, about 4 metres wide and now closed by a gate, with a causeway across the fosse that may be a relatively recent addition; and one to the south-south-east, about 4.4 metres wide, where bank material has slumped into the ditch rather than been cut deliberately. The fosse itself, 2.3 metres wide and 0.4 metres deep, is best preserved along its south-western arc and becomes barely traceable to the north-east. Denis Power, who compiled the record, noted aerial photographs taken in March 2006 as part of the documentation.

The site sits in working pasture on a gentle east-facing slope, and the signs of active farming are visible throughout. Cattle have disturbed the fosse along its eastern section, the interior has been churned by farm machinery, and loose stone eroded from the bank is scattered around the perimeter. Field boundaries press in at the west and south-east, giving the monument little buffer from the surrounding land use. Anyone visiting should expect to be looking at a working field, not a managed heritage site, and should seek landowner permission before approaching. The earthworks reward careful observation from the bank line itself, where the variation in preservation between the south-western and northern arcs becomes apparent on the ground in a way that aerial photographs alone do not quite convey.
