To an untrained eye it reads as a slight unevenness in the field, a faint arc of raised earth that could easily be dismissed as a quirk of the land. It is, in fact, the surviving edge of a ringfort, a type of enclosed settlement that was built in Ireland predominantly during the early medieval period, roughly between the fifth and twelfth centuries. Thousands of these sites survive across the island, many so eroded that only their circular outline gives them away.

The ringfort at Graig takes roughly circular form, measuring approximately 31.5 metres on a northeast to southwest axis. What remains of the enclosing earthen bank stands only around half a metre high, and the external fosse, the shallow ditch that would originally have reinforced the boundary, is described as barely perceptible. A fosse was a standard feature of these earthwork enclosures, dug to provide material for the bank and to add a further deterrent at the perimeter. A field boundary has been built up against the bank on the eastern side at some point, which is a common fate for these sites as later agricultural arrangements absorbed or partially overlaid earlier ones. The interior is level and under pasture. The record was compiled by Denis Power and uploaded in August 2011.

Accessing the site requires crossing private agricultural land, so any visit would need the landowner's permission. Once in the field, the bank is best appreciated by walking the perimeter slowly rather than looking for it from a distance. The slight elevation of the earthwork only becomes coherent when you are close to it and can read the gentle curve of the ground as continuous rather than incidental. There is nothing dramatic to see in the conventional sense, no stonework, no obvious height, no visible archaeology at the surface. What makes it worth seeking out is precisely that quality of near-invisibility, the way a structure that once defined someone's home, farm, and place in the world has been reduced to a barely legible script in the soil.
