That distinction, quiet as it sounds, places it in an intriguing category: a site that is documented, mapped, and visible from the air, yet entirely unexamined on the ground.

A crannog is an artificial or partially artificial island, typically built during the early medieval period in Ireland, constructed from timber, stone, peat, and brushwood, and used as a dwelling or place of refuge. The feature at Cordressogagh appears on both the 1835 and 1908 editions of the six-inch Ordnance Survey map, and again on the current 1:5000 mapping, where it registers as a substantial feature measuring somewhere between twelve and fifteen metres in diameter. It sits within Moneen Lough, a notably rectangular lake measuring around 430 metres on its longer axis, with a broad bay opening out on the opposite north-western shore. Aerial photography confirms what the maps suggest: a cluster of trees rising from the water, the typical silhouette of a crannog that has been left to grow over in the centuries since it was last used. The site was first brought to wider attention by researcher Anne-Karoline Distel, though a full ground-level inspection has yet to follow.
