The site measures roughly 28 metres north to south and 22 metres east to west internally, which gives it the footprint of a large house plot, though what it once enclosed is not known.

The construction is layered in a way that repays a close look. There is an inner earthen bank, then a berm (a flat shelf of ground between two earthworks), and beyond that an outer wall of collapsed stone. This kind of double or composite boundary is sometimes associated with early medieval enclosures, where the distinction between inner and outer zones could carry meaning, whether practical, social, or ritual. At the eastern side, the inner bank still holds something of its original profile, as does the southern arc; elsewhere the ground simply drops away in a low scarp, the bank having spread and settled over centuries. The berm and the outer stone wall are more legible on the western and southern sides, where they have fared better against time and agricultural activity.

The place-name Caherakeeny contains the Irish word cathair, which typically refers to a stone fort or enclosure, suggesting that some memory of a substantial structure persisted in local usage long after the stonework began to collapse. That the surviving fabric is now described as poorly preserved is not a slight against the site so much as an honest account of what the land does to things over a long enough stretch of time.
