The largest island Mainland is often referred to as "the Mainland". It has an area of , making it the sixth-largest Scottish island and the tenth-largest island in the British Isles. The largest settlement and administrative centre is Kirkwall., The North Sea is a marginal sea of the Atlantic Ocean located between Great Britain, Scandinavia, Germany, the Netherlands, Belgium, and France. An epeiric (or "shelf") sea on the European continental shelf, it connects to the ocean through the English Channel in the south and the Norwegian Sea in the north. It is more than long and wide, with an area of around ., The Loch of Stenness is a large brackish loch on Orkney Mainland, Scotland and is named for the parish of Stenness. It is northeast of the town of Stromness, lies immediately to the south of the Loch of Harray and is close to the World Heritage neolithic sites of the Stones of Stenness and Ring of Brodgar. In Old Norse its name was "Steinnesvatn"., A country is a region that is identified as a distinct national entity in political geography. A country may be an independent sovereign state or one that is occupied by another state, as a non-sovereign or formerly sovereign political division, or a geographic region associated with sets of previously independent or differently associated people with distinct political characteristics. Regardless of the physical geography, in the modern internationally accepted legal definition as defined by the League of Nations in 1937 and reaffirmed by the United Nations in 1945, a resident of a country is subject to the independent exercise of legal jurisdiction., There are three related types of Neolithic earthwork that are all sometimes loosely called henges. The essential characteristic of all three types is that they feature a ring bank and ditch, but with the ditch inside the bank rather than outside. Due to the poor defensive utility of an enclosure with an external bank and an internal ditch, henges are not considered to have served a defensive purpose (cf. circular rampart). The three types are as follows, with the figure in brackets being the approximate diameter of the central flat area:, Scotland (Scots: ) is a country that is part of the United Kingdom and covers the northern third of the island of Great Britain. It shares a border with England to the south, and is otherwise surrounded by the Atlantic Ocean, with the North Sea to the east and the North Channel and Irish Sea to the south-west. In addition to the mainland, the country is made up of more than 790 islands, including the Northern Isles and the Hebrides., The Hebrides (Scottish Gaelic: "Innse Gall"; Old Norse: "Suðreyjar") comprise a widespread and diverse archipelago off the west coast of mainland Scotland. There are two main groups: the Inner and Outer Hebrides. These islands have a long history of occupation dating back to the Mesolithic, and the culture of the residents has been affected by the successive influences of Celtic, Norse, and English-speaking peoples. This diversity is reflected in the names given to the islands, which are derived from the languages that have been spoken there in historic and perhaps prehistoric times., Great Britain, also known as Britain , is a large island in the north Atlantic Ocean off the northwest coast of continental Europe. With an area of , Great Britain is the largest European island and the ninth-largest in the world. In 2011 the island had a population of about 61 million people, making it the world's third-most populous island after Java in Indonesia and Honshu in Japan. The island of Ireland is situated to the west of it, and together these islands, along with over 1,000 smaller surrounding islands, comprise the British Isles archipelago., The Loch of Harray is the largest loch of Mainland Orkney, Scotland and is named for the nearby parish of Harray. It lies immediately to the north of the Loch of Stenness and is close to the World Heritage neolithic sites of the Stones of Stenness and Ring of Brodgar. In Old Norse its name was "Heraðvatn"., Technology ("science of craft", from Greek , "techne", "art, skill, cunning of hand"; and , "-logia") is the collection of techniques, skills, methods and processes used in the production of goods or services or in the accomplishment of objectives, such as scientific investigation. Technology can be the knowledge of techniques, processes, and the like, or it can be embedded in machines which can be operated without detailed knowledge of their workings., England is a country that is part of the United Kingdom. It shares land borders with Scotland to the north and Wales to the west. The Irish Sea lies northwest of England and the Celtic Sea lies to the southwest. England is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain (which lies in the North Atlantic) in its centre and south; and includes over 100 smaller islands such as the Isles of Scilly, and the Isle of Wight., Historic Scotland was an executive agency of the Scottish Government from 1991 to 2015, responsible for safeguarding Scotland's built heritage, and promoting its understanding and enjoyment. Under the terms of a Bill of the Scottish Parliament published on 3 March 2014, Historic Scotland was dissolved and its functions were transferred to Historic Environment Scotland (HES) on 1 October 2015. HES also took over the functions of the Royal Commission on the Ancient and Historical Monuments of Scotland., The Standing Stones of Stenness is a Neolithic monument five miles northeast of Stromness on the mainland of Orkney, Scotland. This may be the oldest henge site in the British Isles. Various traditions associated with the stones survived into the modern era and they form part of the Heart of Neolithic Orkney World Heritage Site. They are looked after by Historic Scotland., Heart of Neolithic Orkney refers to a group of Neolithic monuments found on the Mainland, one of the islands of Orkney, Scotland. The name was adopted by UNESCO when it proclaimed these sites as a World Heritage Site in 1999., The Stone Age was a broad prehistoric period during which stone was widely used to make implements with an edge, a point, or a percussion surface. The period lasted roughly 3.4 million years, and ended between 8700 BCE and 2000 BCE with the advent of metalworking., The Northern Isles  is an archipelago comprising a chain of islands off the north coast of mainland Scotland. The climate is cool and temperate and much influenced by the surrounding seas. There are two main island groups: Shetland and Orkney. There are a total of 26 inhabited islands with landscapes of the fertile agricultural islands of Orkney contrasting with the more rugged Shetland islands to the north, where the economy is more dependent on fishing and the oil wealth of the surrounding seas. Both have a developing renewable energy industry. They also share a common Pictish and Norse history. Both island groups were absorbed into the Kingdom of Scotland in the 15th century and remained part of the country following the formation of the Kingdom of Great Britain in 1707, and later the United Kingdom after 1801. The islands played a significant naval role during the world wars of the 20th century., A World Heritage Site is a landmark which has been officially recognized by the United Nations, specifically by UNESCO. Sites are selected on the basis of having cultural, historical, scientific or some other form of significance, and they are legally protected by international treaties. UNESCO regards these sites as being important to the collective interests of humanity., The Neolithic Barnhouse Settlement is sited by the shore of Loch of Harray , Orkney Mainland , Scotland , not far from the Standing Stones of Stenness , about 5 miles north - east of Stromness . It was discovered in 1984 by Colin Richards . Excavations were conducted between 1986 and 1991 , over time revealing the base courses of at least 15 houses . The houses have similarities to those of the early phase of the better - known settlement at Skara Brae in that they have central hearths , beds built against the walls and stone dressers , but differ in that the houses seem to have been free - standing . The settlement dates back to circa 3000 BC. Pottery of the grooved ware type was found , as at the Stones of Stenness and Skara Brae . Flint and stone tools were found , as well as a piece of pitchstone thought to have come from the Isle of Arran . The largest of the original buildings was House 2 . It was double - sized , featuring a higher building standard than the other houses and unlike the others ( rebuilt up to five times ) seems to have remained in use throughout the inhabited period of the settlement . The houses were clustered around a central open area which was divided into areas for making pottery and the working of flint , bones and hides . Evidence suggests that Barnhouse was abandoned around 2600 BC. After Barnhouse ceased to be occupied , another structure was added , partially on top of the earlier building plans . This building ( known as Structure 8 ) had a room about 7 m ( 23 ft ) square with walls 3 m ( 10 ft ) thick and an entrance facing towards the north west so that the midsummer sunset shines along the passageway , with similarities to some chambered cairns . The structure was surrounded by a clay platform . The entrance through this was aligned with Maeshowe . The structure is assumed to have served as a ceremonial site rather than as a dwelling . It is thought to be closely linked with the nearby Stones of Stenness . Some of the hearth slabs from the structure may have been moved to the Stones . This site is accessible to the public via a footpath from the Standing Stones of Stenness ., Old Norse was a North Germanic language that was spoken by inhabitants of Scandinavia and inhabitants of their overseas settlements during about the 9th to 13th centuries., The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a sovereign country in western Europe. Lying off the north-western coast of the European mainland, it includes the island of Great Britain (the name of which is also loosely applied to the whole country), the north-eastern part of the island of Ireland, and many smaller islands. Northern Ireland is the only part of the UK that shares a land border with another sovereign statethe Republic of Ireland. Apart from this land border, the UK is surrounded by the Atlantic Ocean, with the North Sea to its east, the English Channel to its south and the Celtic Sea to its south-south-west, giving it the 12th-longest coastline in the world. The Irish Sea lies between Great Britain and Ireland. With an area of , the UK is the 78th-largest sovereign state in the world and the 11th-largest in Europe. It is also the 21st-most populous country, with an estimated 65.1 million inhabitants. Together, this makes it the fourth most densely populated country in the European Union., The Irish Sea (, , , Ulster-Scots: "Airish Sea"), separates the islands of Ireland and Great Britain. It is connected to the Celtic Sea in the south by St George's Channel, and to the Inner Seas off the West Coast of Scotland in the north by the North Channel. Anglesey is the largest island within the Irish Sea, followed by the Isle of Man. The sea is occasionally, but rarely, referred to as the Manx Sea., The Ring of Brodgar (or Brogar, or Ring o' Brodgar) is a Neolithic henge and stone circle about 6 miles north-east of Stromness on the Mainland, the largest island in Orkney, Scotland. It is part of the UNESCO World Heritage Site known as the Heart of Neolithic Orkney., Harray (Old Norse: "Herað" - cf Harris) is a former parish on Mainland, Orkney, Scotland, now merged with Birsay. It has the unique distinction of being the only landlocked parish on the islands; however, it is next to the freshwater Loch of Harray., The Neolithic Age, Era, or Period, or New Stone Age, was a period in the development of human technology, beginning about 10,200 BC, according to the ASPRO chronology, in some parts of the Middle East, and later in other parts of the world and ending between 4,500 and 2,000 BC., Subject: barnhouse settlement, Relation: part_of, Options: (A) 1937 (B) art (C) atlantic ocean (D) back (E) country (F) division (G) earth (H) england (I) europe (J) european union (K) government (L) heart of neolithic orkney (M) hebrides (N) honshu (O) industry (P) ireland (Q) irish sea (R) islands (S) japan (T) java (U) language (V) march (W) may (X) middle east (Y) neolithic (Z) ocean ([) orkney islands (\) outer hebrides (]) parish (^) part (_) political geography (`) population (a) production (b) ring (c) science (d) scottish parliament (e) sea (f) settlement (g) sovereign state (h) state (i) stone age (j) technology (k) the collection (l) the middle (m) united nations (n) world heritage site
