Knap of Howar is a neolithic settlement on Papa Westray (one of the Orkney Islands) in Scotland. The farm was occupied from about 3700 to 2800 BC. The farm consists of two buildings: One has been interpreted as house where people lived, the other as a workshop of sorts.The houses have no windows, both entries face the sea. It is believed that the houses where lit by fires.
