The site is technically inaccessible, swallowed by overgrowth, yet its outline has been legible on Ordnance Survey maps since 1842, first as a simple hachured circle, then, by 1904, unmistakably bivallate, meaning it has a double ring of banks enclosing a central space roughly 25 metres across. The road to the north-east and a field boundary to the south-east have each taken a bite out of the perimeter, but enough survives to trace the structure from east-south-east around to the west.

This is a rath, the Irish term for a ringfort, the kind of enclosed farmstead that was built across Ireland in early medieval times, typically between the sixth and tenth centuries, to shelter a family, their livestock, and their stores. What makes this particular example more than ordinarily interesting is the detail preserved by a 1934 account from a researcher named Bowman, who visited when the site was still accessible and recorded it under its Irish name, 'Lisin na Mealbhog', on land belonging to a T. O'Connor. Bowman measured the inner rampart at around seven feet high and the outer at five feet, with an intervening fosse, that is, a ditch, some fifteen feet wide. The overall diameter he put at thirty-five yards, somewhat larger than the modern survey estimate. Concealed within the northern half of the interior is a souterrain, an underground stone-lined passage or chamber that was commonly used in early medieval Ireland for storage or as a place of refuge. Just to the west of the ringfort sits what may be a ringbarrow, a low circular burial mound, which, if confirmed, would suggest the site sits within a landscape carrying memories considerably older than the fort itself.
