The only clue to its existence is a souterrain entrance, an opening into one of those stone-lined underground passages that were commonly built in early medieval Ireland, used variously for storage, refuge, or concealment. Were it not for that single feature breaking the surface, the site would be entirely invisible.

The fort was recorded as a physical presence on the 1842 edition of the Ordnance Survey six-inch map, where it was both hachured, meaning its outline was drawn with short directional marks to indicate an earthwork, and named. By the time the 1915 edition appeared, the hachuring was gone and only the name remained, suggesting the earthwork had already been substantially levelled by agricultural improvement in the intervening decades. Later surveys classified it as an enclosure, a broad category covering the kind of ringfort-type monuments that were once among the most common field monuments in Ireland. The souterrain associated with it, catalogued separately, is described as a fine example, which makes the otherwise blank field around it all the more quietly strange.
