Known locally as Still Island, it carries a tradition that people once lived there, and the physical evidence, when the water obliges, suggests this is more than folk memory.

The island is believed to be a crannog, a type of artificial or partly artificial island dwelling common in Ireland and Scotland from the Bronze Age through to the early medieval period and occasionally beyond. Crannogs were typically constructed by piling timber, stone, peat, and brushwood into shallow lake water, creating a raised platform that offered both security and seclusion. Still Island fits the profile: it is small, circular, and set in a lake. What makes the site particularly interesting is what drainage work in the surrounding area has revealed. Lowering the water level exposed what appears to be a causeway connecting the island to the northern shore, visible now as a narrow band of reeds cutting across the lake surface. Submerged causeways of this kind are a recognised feature of crannog sites, providing a concealed or controlled route between island and land that would have been invisible or impassable to anyone unfamiliar with it.

The site has been assessed only from the lake shore, so the island's interior remains uninvestigated and its precise date unknown. The local tradition of habitation, combined with the emerging causeway line, leaves a reasonable case open, though one that awaits closer scrutiny.
