context_page_description: The Mainland is the main island of Orkney, Scotland. Both of Orkney's burghs, Kirkwall and Stromness, lie on the island, which is also the heart of Orkney's ferry and air connections.
  Seventy-five per cent of Orkney's population live on the island, which is more densely populated than the other islands of the archipelago. The lengthy history of the island's occupation has provided numerous important archaeological sites and the sandstone bedrock provides a platform for fertile farmland. There is an abundance of wildlife, especially seabirds.
context_section_description: The western section of the island contains numerous Neolithic and Pictish constructions.
  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.
  Other sites of interest include St. Magnus Cathedral and the ruin of the Bishop's Palace in Kirkwall, the Earl's Palace, a ruined 16th-century castle in Birsay parish, and Skaill House, a manor house and museum near Skara Brae.
  Viking settlers comprehensively occupied Orkney, and Mainland became a possession of Norway until being given to Scotland during the 15th century as part of a dowry settlement. Evidence of the Viking presence is widespread, and includes the site of a settlement at the Brough of Birsay, the vast majority of place names, and runic inscriptions at Maeshowe and other ancient sites.
  Stromness is of relatively recent origin, being first recorded as the site of an inn in the 16th century, although the name is of Norse origin. Stromness became important during the late 17th century, when England was at war with France and shipping was forced to avoid the English Channel. Ships of the Hudson's Bay Company were regular visitors, as were whaling fleets.
  The Churchill Barriers are a series of four causeways with a total length of 1.5 miles (2.4 km). They link the south of Mainland in the north to the island of South Ronaldsay via Burray and the two smaller islands of Lamb Holm and Glimps Holm. On 14 October 1939, the Royal Navy battleship HMS Royal Oak was sunk at her moorings within the natural harbour of Scapa Flow, by the German U-boat U-47 under the command of Günther Prien. U-47 had entered Scapa Flow through Holm Sound, one of several eastern entrances to Scapa Flow. To prevent further attacks, Winston Churchill ordered the construction of permanent barriers. They now serve as road links, carrying the A961. Work began in May 1940 and the barriers were completed in September 1944, but were not officially opened until 12 May 1945, four days after the end of World War II in Europe.
