In most of Europe neolithic communities live in villages of timber houses, often with a communal longhouse as the central feature (one, discovered at Bochum in Germany, is some 65 metres in length). But along the entire Atlantic coast, from Spain to Britain and Denmark, the focus of village life is a communal tomb, around which simple huts are clustered. The tomb chambers of these regions introduce the tradition of stonework which includes passage graves and megaliths, also the very solid domestic architecture of Skara Brae.
