The ground across a pasture atop a sand ridge holds only low undulations where a substantial earthwork once stood, and without knowing what to look for, a visitor might cross the site without registering anything at all. That near-invisibility is itself part of the story. Ringforts, or raths, were enclosed farmsteads of the early medieval period, typically circular or oval earthen banks surrounding a homestead, and they number in the tens of thousands across Ireland. Most have fared better than this one.

By the time the Ordnance Survey produced its six-inch maps in 1842, the enclosure at Russelhill was already being recorded as a hachured subrectangular area, roughly 35 metres north to south and 20 metres east to west. Sixty years later, the 1904 revision shows a slightly larger raised oval form, measuring around 40 metres by 30 metres, by then absorbed into the field fence system. A 1939 account by Hartnett recorded it as oval in plan, approximately 130 feet by 100 feet, raised five to six feet above the surrounding ground to the north, east, and south, with a boundary fence running along its western edge. That description captures the fort at a moment when it still held some presence in the landscape. It has since been levelled, leaving only the faint rolling of the ground beneath the pasture to indicate where the bank once ran.
