That ambiguity is rather the point. A crannog is a man-made island, typically constructed during the early medieval period by piling up layers of timber, stone, peat, and brushwood in shallow water, and then used as a defended homestead or settlement. What lies here, if anything coherent remains at all, has never been properly confirmed.

The site enters the record through a brief observation made by G.H. Kinahan in 1872, who noted that during periods of low water, a circle of stones became visible, with a small island-like feature near its centre. He interpreted this as the remnant of some artificial structure, most likely a crannog or lake stone-dwelling, though he stopped short of certainty. That cautious phrasing has proved prescient. When the site was visited at a later date, nothing at all was visible, leaving Kinahan's description as the sole substantive account. Whether the water level was simply too high, or whether the structure has deteriorated beyond recognition, is unknown.
