Skara Brae () is a large stone-built Neolithic settlement on the Bay of Skaill on the west coast of mainland Orkney, Scotland. It consists of ten houses, and was occupied from roughly 3100–2500. It is Europe's most complete Neolithic village. The level of preservation is such that it is a main part of the UNESCO World Heritage Site of the Heart of Neolithic Orkney. This is one of four UNESCO World Heritage Sites in Scotland, the others being the Old Town and New Town of Edinburgh; New Lanark in South Lanarkshire; and St Kilda in the Western Isles.
