The only one in the Western Isles
You can't miss Kisimul Castle - you'll see it as you arrive on the ferry to Barra. It's the only surviving medieval castle in the Western Isles, built on a rock in the middle of the bay. It's a five-minute boat trip from Castlebay, and you can explore the three-storey tower house, once the seat of the Chiefs of Clan Macneil. As you'd expect, the view from the battlements is spectacular.
