Mousa

United Kingdom

Mousa is a small uninhabited island in the Shetland Islands of Scotland, south of Lerwick. It holds the finest surviving broch in the world — an Iron Age stone tower standing 13 meters high after two thousand years. Visitors land in summer to climb the broch's internal stair, see the storm petrels that nest in its walls by the thousand — watched at dusk — the seals on the shore, and the ancient engineering of Scotland's best-preserved roundhouse tower.
