About island brochs & forts
All brochs & forts →Brochs are drystone towers built over two thousand years ago, found only in Scotland, and many of the best are on islands. Here you will find the brochs, duns and prehistoric forts on the islands we cover, from Shetland and Orkney to the Hebrides and the west of Ireland.
