 Initially, their power base was on the shores of Loch Finlaggan in northeastern Islay, near the present-day village of Caol Ila.Successive chiefs of Clan Donald were proclaimed Lord of the Isles there, upon an ancient seven-foot-square coronation stone bearing footprint impressions in which the new ruler stood barefoot and was anointed by the Bishop of Argyll and seven priests.The Lord's advisory ""Council of the Isles"" met on Eilean na Comhairle ("Council Island"), in Loch Finlaggan on Islay, within a timber framed crannog that had originally been constructed in the 1st century BC.
