It sits just off the southern shore of Mill Lough, a kidney-shaped body of water measuring roughly 550 metres east to west and 330 metres north to south. The island is modest, about 14 metres across, and dense with trees. What makes it quietly remarkable is the strong likelihood that it is not a natural feature at all, but a crannog, an artificially constructed or artificially enlarged island built from timber, stone, peat, and brushwood, used as a defended dwelling place during the early medieval period and sometimes well beyond it.

The island first appears on the 1908 edition of the Ordnance Survey six-inch map and is shown on subsequent editions too, which means its physical presence has been a matter of cartographic record for well over a century. It was first identified as a probable crannog by Anne-Karoline Distel, and aerial photography confirms a tree-covered feature consistent with that identification. Despite this, the site has never been visited by researchers. The trees that now cover it, visible in every aerial image taken of the area, likely obscure whatever structural evidence might remain at the surface, but crannogs frequently preserve organic material exceptionally well beneath waterlogged conditions, making even unexcavated examples of considerable archaeological interest.
