Dun Carloway Broch

By the west coast stands Dun Carloway Broch (16mi/25.6km northwest of Stornaway). This Pictish fortified farm dates from the fourth century B.C. It stands at a height of about 164ft/50m above sea level and measures 52ft/16m in diameter. The double walls are 10ft/3m thick in places and on one side they reach a height of 33ft/10m. Several steps form a link inside the mortar-free double walls and four chambers can be made out within the inner wall.
