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 consists of ten clustered houses and was occupied from roughly 3180 BCE–2500 BCE. Around 2500 BCE, after the climate changed, becoming much colder and wetter, the settlement may have been abandoned by its inhabitants. There are many theories as to why the people of Skara Brae left, particularly popular interpretations involve a major storm. Evan Hadingham combined evidence from found objects with the storm scenario to imagine a dramatic end to the settlement.
