This is what remains, or what may remain, of Knockanroe Fort, and the ambiguity is precisely the point. The mound measures roughly 36.5 metres east to west and 48.5 metres north to south, standing about two metres at its highest point on the northern side. Its top is fairly level before merging almost imperceptibly into broadly sloping sides, giving the whole thing a gently humped profile rather than the sharper silhouette one might associate with a deliberately built earthwork. Whether that profile reflects the original shape of the enclosure, or whether the fort was simply constructed on top of a natural rise in the ground, remains an open question.

What can be said with more certainty is that something was once here. The Ordnance Survey's six-inch map of 1838 marks a circular embanked enclosure at this location, with a diameter of roughly twenty to twenty-five metres, and names it Knockanroe Fort. Embanked enclosures of this kind, often referred to locally as ring forts or raths, were typically used as enclosed farmsteads during the early medieval period in Ireland, though the term fort can be misleading given that domestic use was far more common than any military function. By the time later map editions were produced, the enclosure itself was no longer depicted; the site is marked simply as "Knockanroe Fort (Site of)", the cartographic shorthand for something that has been noted, named, and then effectively lost. A property fence now crosses the southern edge of the mound, and a stream about a hundred metres to the east marks the townland boundary, lending the site a quietly marginal quality, sitting at the edge of things in more ways than one.
