Broch of Borwick

Iron Age broch perched on a cliff-top promontory 20 metres above the sea on the west coast of Mainland, Orkney. Built around 500 BC, the broch has an external diameter of 17 metres and walls up to 5 metres thick, standing to a maximum height of 2.6 metres. The eastern half and entrance passage are well preserved, but the western side has been lost to coastal erosion. Excavated by W. G. T. Watt in 1881, finds included combs, querns, stone gaming pieces, and an iron rod. Below the broch lies a cave called Hell's Mouth, from Old Norse hellir.
