The ringfort that once stood here has been so thoroughly levelled that local memory has quietly reassigned its name to a quarry lying roughly seventy metres to the west-northwest, and it is the quarry that is now called "the fort" in the area.

Ringforts, known in Irish as raths, were enclosed farmsteads typically built during the early medieval period, their circular earthen banks defining a protected space for a family and their livestock. The Ballymague example was recorded on the Ordnance Survey six-inch map of 1842, where it appeared as a hachured circular enclosure with a diameter of around twenty metres. That cartographic trace is now one of the more reliable pieces of evidence for the site's original form. The earthwork itself has been levelled, though a slight scarp still curves across the pasture in an arc of approximately 26.5 metres in diameter, running from north-northwest to south-southeast. The interior of the former enclosure slopes downward toward the east, following the natural lie of the hillside.

What remains, then, is a landscape that holds the ghost of a structure rather than the structure itself: a faint curve in a field, a misplaced place-name, and a nineteenth-century map as the clearest record of what was once there.
