Cenél Loairn

The Cenél Loairn, the descendants of Loarn mac Eirc, controlled parts of northern Argyll around the Firth of Lorne, most probably centred in Lorne but perhaps including the islands of Mull and Colonsay, Morvern and Ardnamurchan. The boundary to the east was the Druim Alban mountain ridge that separated Dál Riata from Pictland. The chief places of the kingdom appear to have been at Dun Ollaigh, near Oban and Dunadd near Crinan. The chief religious site may have been on Lismore, later the seat of the High Medieval bishop of Argyll.
