Most of the best known Neoloithic ancient monuments are located in west Mainland, which includes the "Heart of Neolithic Orkney", a UNESCO World Heritage Site. This comprises the large chambered tomb of Maes Howe, the ceremonial stone circles the Standing Stones of Stenness and the Ring of Brodgar and the Neolithic village of Skara Brae, together with a number of unexcavated burial, ceremonial and settlement sites. The group constitutes a major prehistoric cultural landscape which gives a graphic depiction of life in the north of Scotland some 5,000 years ago. Nearby is the Barnhouse Settlement, a smaller cluster of prehistoric buildings.
