The ground lifts barely half a metre above the surrounding land, forming a roughly circular platform around twenty-two metres across. It is the kind of feature that a casual walker might register only as an odd unevenness underfoot, yet it represents a form of settlement that was once extraordinarily common across the Irish countryside.

Ringforts, known in Irish as raths when they were earthen rather than stone-built, were the standard dwelling enclosures of early medieval Ireland, typically dating from roughly the fifth to the twelfth centuries. They consisted of a raised, roughly circular area enclosed by one or more earthen banks and external ditches, and they served as farmsteads for individual family units. At Doony, the 1842 Ordnance Survey six-inch map recorded the site as a hachured circular enclosure of approximately twenty metres in diameter, meaning that by the mid-nineteenth century it was already a ruin but still legible enough to be mapped. What survives today is the levelled remnant of that enclosure, and a faint depression around the raised area which may represent the original fosse, the outer ditch that would once have defined and defended the perimeter. The correspondence between the mapped diameter and the surviving platform suggests the earthwork has compressed and spread rather than been entirely removed, which is itself a small piece of information about how these sites degrade over time rather than simply disappear.
