Broch of Borwick

The Broch of Borwick is an Iron Age broch located on Mainland, Orkney, Scotland [1]. The broch stands on top of a cliff-top promontory 20 metres above the sea [1]. The broch has an external diameter of 17 metres and an internal diameter of 8 metres [1]. The walls which are 3.5 to 5 metres thick currently stand to a maximum height of 2.6 metres [1]. The eastern half of the broch and the entrance passage are well preserved, but the western half has been destroyed by erosion [1]. The site was excavated in 1881 by W. G. T. Watt, and the interior was cleared of debris [1]. Finds included several combs, a small whale vertebra cup, a spindle whorl, a stone gaming piece, a whetstone, hammerstones, some stone knives and choppers, an iron rod, and some querns [1].
