What was once a crannog, an artificial or artificially enlarged island built out into a lake as a defended dwelling place, typically during the early medieval period, now sits on reclaimed land, left stranded by the Inny River drainage scheme carried out in the late 1960s. The lake receded, the shoreline shifted, and a structure that once would have required a boat or a carefully managed causeway to reach can now be approached on foot across ground that was, within living memory, submerged.

The site itself retains a distinctive character despite the changed landscape. It presents as a tree-covered island mound, its surface broken by large rock outcrops rather than the more typical layered timbers, brushwood, and peat associated with crannog construction. Roughly fifty metres to the north lies a second crannog, recorded separately, and the two appear to be connected by a stone-lined causeway, raising the possibility that they functioned together as a conjoined complex. Such arrangements, where multiple platforms were linked across open water, are known elsewhere in Irish lake archaeology, though the precise relationship between these two features at Lough Iron remains a matter of interpretation.
