Promontory forts, known in Irish archaeology as dúnta, make use of a projecting tongue of land, cutting it off from the mainland with one or more earthen banks and ditches. The result is a fortified enclosure that requires far less effort to defend than a site surrounded on all sides, since the cliffs and water secure the remaining perimeter. The Tralong example belongs to this coastal tradition, sitting where Cork meets the Atlantic in a stretch of coastline that still feels genuinely remote.
