It is a cliff-edge fort, a type of enclosure that uses the natural drama of riverbank or coastal scarps in place of fully constructed defences, allowing the builders to rely on the landscape itself to do much of the protective work. This example sits in the south-western angle of the confluence, its roughly segmental plan measuring around 17 metres east to west and 8 metres north to south.

The enclosure is defined on one side by a scarp running east to west, now heavily obscured by dense overgrowth, and on its straight northern face by a steep earthen scarp roughly 4 metres wide and 1.4 metres high. That northern edge would have looked directly out over the Multeen before it joins the larger Suir, giving any occupants a commanding view of both waterways. The interior is level, and at least one mature beech tree now grows within it, rooting the fort into a landscape that has long since shifted from whatever use the enclosure once served to improved agricultural pasture around it. The monument itself sits in an ungrazed margin, which accounts for the thick vegetation that now makes its earthworks difficult to read clearly from ground level.

A fisherman's pathway runs around the exterior of the fort along the riverbanks to the north and east, which means the site is approached not through the fields but along the water's edge, giving the odd impression that the fort is glimpsed from the outside in, framed by the river rather than the land behind it.
