It is easy to overlook, barely three metres across at its widest point, and parts of its eastern wall have disappeared entirely beneath vegetation creeping up from the river bank beside it. What survives, particularly along the northern arc, is a collapsed drystone wall, that is, a wall built without mortar, relying entirely on the careful stacking of stone, still standing to around 1.4 metres in places and nearly a metre thick. Someone, at some point, also piled field-clearance stones against the outside of the northern and southern walls, the kind of practical tidying-up that farmers have always done, and which over time makes it harder to read where the original structure ends and later agricultural activity begins.

The builders made one particularly telling decision: the northern portion of the interior floor was cut back into the hillside rather than built up from it. This technique, sometimes called scarping, levels out a sloping interior without requiring a tall retaining wall on the uphill side, and it tells us something about the care taken in the construction. The entrance faces west. The structure is a hut site, a term that covers a broad category of small, often prehistoric or early medieval dwellings found across Kerry and the wider Irish landscape, many of them associated with seasonal farming or transhumance, the practice of moving livestock to upland pastures in summer. Whether this particular example belongs to that tradition is not recorded, but its position, on a riverside slope with a long view towards the bay, fits a pattern seen repeatedly across south-west Kerry.
