Dun Beag is one of the best preserved brochs and a good example of a broch tower.
Brochs only appear in Scotland. They are dry stone structures formed of two concentric walls with a narrow entrance passage. Stone stairs ran between the walls to provide access, perhaps to upper floors, and the top.
Scotland’s brochs were built in the Iron Age, first emerging about 2,300 years ago. Their use continued until the middle of the first millennium CE.
@ChaHarper We're so glad we got to visit Dun Beach when we visited Skye this past May. It's a very special place.
@ChaHarper There's the substantial remains of a building with many of the features of a broch, including the hollow centre, and the double walls and apparent accommodation within them, but roughly rectangular in plan, at Castlehaven Bay near Borgue, in Galloway. Whether it's a related to brochs or not I'm not qualified to say.
@ChaHarper they are tantalisingly similar to the nuraghi of Sardinia.
And I can’t remember where I read it but I seem to recall that our sheep are descended from Sardinian sheep.
