Midhowe Chambered Cairn is a large Neolithic chambered cairn located on the south shore of the island of Rousay, Orkney, Scotland. The name "Midhowe" comes from the Iron Age broch known as Midhowe Broch, that lies just west of the tomb. The broch got its name from the fact that it is the middle of three such structures that lie grouped within 500 metres (1,600 ft) of each other and Howe from the Old Norse word haugr meaning mound or barrow. Together, the broch and chambered cairn form part of a large complex of ancient structures on the shore of Eynhallow Sound separating Rousay from Mainland, Orkney.
