Standing at ground level in the pasture, nothing announces it. The enclosure is simply there, absorbed into the grass, its circular outline legible only from above or through the finer detective work of old maps.

A rath is an earthen ringfort, the most common type of early medieval settlement monument in Ireland, typically consisting of a raised circular bank enclosing a domestic area. This particular example measures approximately forty metres in diameter and appears on both the 1846 Ordnance Survey six-inch map and the revised edition of 1894 to 1895, each time as a clear circular enclosure. It was likely recorded in the 1840s as Gortdarrig Fort, noted at that time as lying on the eastern side of the Gortderrig townland. That it was given a name at all suggests it was still recognisable in the landscape during the nineteenth century, even if the earthworks have since flattened to the point of invisibility.
