No earthwork survives above ground. Nothing catches the eye. What remains is a field on a low rise in County Mayo, a line in the 1838 Ordnance Survey six-inch map that had already disappeared by the 1916 edition, and a thread of local memory insisting that a fort once stood here.

A rath, the Irish term for a roughly circular earthen enclosure typically used as a farmstead during the early medieval period, was recorded in the mid-nineteenth century as an oval embanked enclosure measuring approximately 25 metres east to west and 20 metres north to south. Writing in 1911, a historian named Knox described what is almost certainly the same feature: an earthen fort some 30 yards in diameter, sitting in an angle of the Owencam river with a scarp, or steep face, of ten feet on its northern side above the marsh. That northern drop still makes sense in the landscape today. The ground falls away from the rise towards a stream and an expanse of low-lying pasture, with an esker ridge, a long gravel bank left behind by glacial meltwater, visible further to the north. The position is a classic one, a modest elevation above wet ground offering both drainage and a degree of natural defence. Complicating the picture is an old sandpit, now partly infilled, that cuts into the eastern side of the rise. Whether it contributed to the obliteration of the earthwork or simply followed it is unclear, but between the sandpit, agricultural improvement, and the passage of time, whatever Knox saw has long since gone.
