[Ir., primrose (?) fort].
Fortress cited in several OIr. narratives, coextensive with the modern village of Dunseverick, 4 miles N of Bushmills, on the north coast of Northern Ireland. Residence of King Eochaid, who gave his daughter in marriage to Rónán in the hopes that she would fall in love with Máel Fothartaig in Fingal Rónáin [How Rónán Slew His Son]. The citation of Dún Sobairche in Táin Bó Cuailnge [Cattle Raid of Cooley] provokes questions; as Medb captures the place after turning from the north, it could hardly be identical with Dunseverick. Gene Haley, geographer of the Táin, suggests the name here should be Dún Lethglaise, coextensive with modern Down-patrick, Northern Ireland.
