No earthen bank, no ditch, no obvious hollow marks the spot. The only reason anyone knows it was there at all is a circle drawn on the first edition of the Ordnance Survey six-inch map, where it was recorded as a roughly circular enclosure about thirty-five metres across.

Ringforts, or raths, were the most common form of enclosed settlement in early medieval Ireland, typically consisting of a raised earthen bank surrounding a farmstead or homestead. They were built in their thousands between roughly the fifth and twelfth centuries, and enough survive across the country to make their shape immediately familiar in the landscape. The one at Ballyeighter has not fared so well. What the map captured in the nineteenth century has since been lost entirely to agricultural use, the gradual flattening that comes from generations of ploughing, grazing, and land improvement. There may be one faint echo of the original structure: a curving townland boundary that bends from the south-west, round through west, and up to the north-north-east, following a line that might overlie the old enclosure beneath it. Boundaries of this kind sometimes preserve the ghost of earlier features simply because field edges and parish lines tend to be conserved even when the earthwork they once traced has long since vanished.
