Dun Carloway is a broch, one of the tall round towers that Iron Age people built across northern and western Scotland roughly 2,000 years ago, stacked from stone without any mortar. It stands on a rocky rise looking out over the moor and sea, and it is among the best preserved anywhere: on one side the wall still climbs to about nine metres, so you get a real sense of how these towers loomed. The wall is hollow, built as two skins with a stair and galleries running up between them, a clever bit of drystone engineering that let the whole thing stand so high. Nobody is sure exactly how brochs were used, whether as a chief’s stronghold, a status symbol, or a farmstead built to impress, but the height and the thick walls clearly mattered to whoever raised them. Historic Environment Scotland looks after the site and it is free to visit, with a small visitor centre nearby. It pairs well with the Calanais or Callanish Standing Stones to the south and the restored Gearrannan Blackhouse Village up the coast.
