Caledonia was the Latin name used by the Roman Empire to refer to the forested region in the central and western Scottish Highlands, particularly stretching through parts of what are now Lochaber, Badenoch, Strathspey, and possibly as far south as Rannoch Moor, known as Coed Celedon to the native Brython (Britons). Today, it is used as a romantic or poetic name for all of Scotland.
