This evening I am presenting some images of a recent visit to Lewis in the Outer Hebrides.

Below are images of a 2000 year old iron age Broch which is located at Carloway above Loch an Duin on a rocky knoll. Brochs are unique to Scotland and may have been constructed as combined high status and defensive dwellings. They were built with two concentric walls of stone with a stairway or gallery within the walls, a feature which may have been a very effective climate control system.
