The positioning is deliberate and telling. Early medieval farmers and their families built these ringforts, known in Irish as raths, across the Irish countryside in their thousands, and the elevated ground at Boolteenagh would have offered both visibility and a degree of natural defence to whoever once lived within its banks.

The fort is a neat circle, measuring 41 metres across in both directions, enclosed by an earthen bank that still stands to a height of just over two metres. Beyond the bank runs an external fosse, a defensive ditch, cut to a depth of 0.7 metres. A gap in the bank, roughly 1.8 metres wide and accompanied by a causeway across the fosse, marks what was once the entrance. Inside the enclosure, there is evidence of a possible souterrain, an underground stone-lined passage or chamber of the kind commonly associated with Irish ringforts, typically used for storage or as a refuge. These features, the bank, the fosse, the causeway entrance, and the souterrain, are characteristic of the rath type, which dates broadly to the early medieval period, roughly the fifth to twelfth centuries. The site survives in pasture, grazed but largely intact, sitting quietly above the surrounding landscape in the way these places so often do.
