A stylised diagram of the photogenic castle in Loch Duich, western highlands of Scotland. Eilean Donan, which means "island of Donnán", is named after Donnan of Eigg, a Celtic saint martyred in 617. Donnán is said to have established a church on the island, though no trace of this remains. The castle was founded in the thirteenth century, and became a stronghold of the Clan Mackenzie and their allies the Clan Macrae. In the early eighteenth century the Mackenzies' involvement in the Jacobite rebellions led to the castle's destruction by government ships in 1719.
