The rath, a univallate ringfort, meaning one enclosed by a single earthen bank, sits on a gently south-west facing slope above Ventry Harbour on the Dingle Peninsula, its roughly circular form still legible despite centuries of absorption into the surrounding field system. Where the enclosing bank has not been pressed into service as a field boundary and faced with drystone masonry, it survives to about 1.5 metres in height. The main entrance gap, 2.15 metres wide and facing south-east, retains an upright slab along its southern edge; a second gap to the north-east is a later, secondary addition.

The interior is where the real losses accumulate. Earlier surveys recorded a circular stone ruin roughly 3.65 metres in diameter and 1.5 metres high, a hut structure from which a souterrain, an underground stone-lined passage of the kind commonly associated with early medieval settlement, extended eastward. That passage was said to reach as far as a large oval cairn, composed of mixed earth and stone, measuring roughly eleven metres north to south and eight metres east to west, which still stands about fifty metres to the north-east. The hut, however, is no longer extant. Where it stood, the only traces are two irregular depressions, each about 0.75 metres deep, their outlines vague enough to suggest collapse rather than deliberate clearance. The souterrain's course, if it survives at all, is unverifiable from the surface. The cairn endures, sitting at the edge of the complex like a full stop to a sentence whose middle has been erased. The site's Irish name, Lios Coinín Doinn, adds a further layer of ambiguity; its meaning connects to a personal name or a description of colour, though the specific reference is now obscure. J. Cuppage documented the complex in the 1986 Corca Dhuibhne archaeological survey of the Dingle Peninsula, and that account remains the principal record of what was once visible here.
