The site is pasture now, and what remains is simply a level platform of ground, roughly twenty metres across, where the earthworks have been erased almost entirely.

A rath is an earthen ringfort, typically a circular enclosure defined by one or more banks and ditches, used as a farmstead during the early medieval period in Ireland. Thousands survive across the country in varying states of preservation, but this one at Knockaninane has fared poorly. The 1894 Ordnance Survey six-inch map recorded it as a circular enclosure with a diameter of approximately thirty metres, which gives some sense of its original scale. By the time the site was examined more recently, even the remnant of bank along the northern arc, which had still been visible at some point, had been levelled by the landowner. What the map preserved in outline, the land itself no longer shows.
