Skara Brae /ˈskɑːrə ˈbreɪ/ is a large stone-built Neolithic settlement, located on the Bay of Skaill on the west coast of mainland Orkney, Scotland. It consists of ten clustered houses, and was occupied from roughly 3100-2500BC. It is Europe's most complete Neolithic village and the level of preservation is such that it has gained UNESCO World Heritage Site status.
Until 1850, Skara Brae lay under years of soil sediment when in the winter of that year a large storm stripped the grass from the large mound known as Skerrabra. The outline of several of stone buildings was revealed and initial excavations were undertaken by William Watt, the laird of Skaill. It was fully excavated between 1928 and 1930 by Vere Gordon Childe following another storm in 1926.
Skara Brae's inhabitants were apparently makers and users of grooved ware. The houses used earth sheltering but, being sunk into the ground, they were built into mounds of pre-existing domestic waste (rubbish) known as "middens". Although the midden provided the houses with a small degree of stability, its most important purpose was to act as a layer of insulation against Orkney's harsh winter climate. On average, the houses measure 40 square metres in size with a large square room containing a large hearth which would have been used for heating and cooking. As few trees grow on the island, the people of Skara Brae used driftwood and whalebone, with turf thatch, to roof their dwellings.
