A rath is an early medieval earthen ringfort, typically a roughly circular enclosure defined by a bank and ditch, used as a farmstead and sometimes a place of modest status. This one measured approximately thirty metres in diameter, and while it has been levelled almost entirely, the southern arc survives as a faint scarp, a barely perceptible change in the ground that you might walk across without registering it as anything other than a slight unevenness in the field.

What makes its former presence knowable is cartographic rather than physical. The enclosure appears on Ordnance Survey six-inch maps from both 1838 and 1929, shown as a roughly circular embanked feature, which means it was still visible and mappable well into the twentieth century before being lost to agricultural levelling at some point after that. The site is described as a possible rath, a cautious classification that reflects the difficulty of confirming function and date when so little earthwork survives. Seventy metres to the east lies a cashel, a stone-built equivalent of a ringfort, which raises the quiet question of whether two distinct communities once occupied this same patch of Mayo hillside, or whether the structures belonged to the same extended settlement at different periods.
