Skara Brae is a stone-built Neolithic settlement, located on the Bay of Skaill on the west coast of Mainland, the largest island in the Orkney archipelago of Scotland. It consisted of ten clustered houses, made of flagstones, in earthen dams that provided support for the walls; the houses included stone hearths, beds, and cupboards. A primitive sewer system, with "toilets" and drains in each house, included water used to flush waste into a drain and out to the ocean. Read more on Wikipedia
