Context: A castle (from ) is a type of fortified structure built in Europe and the Middle East during the Middle Ages by nobility. Scholars debate the scope of the word "castle", but usually consider it to be the private fortified residence of a lord or noble. This is distinct from a palace, which is not fortified; from a fortress, which was not always a residence for nobility; and from a fortified settlement, which was a public defence  though there are many similarities among these types of construction. Usage of the term has varied over time and has been applied to structures as diverse as hill forts and country houses. Over the approximately 900 years that castles were built, they took on a great many forms with many different features, although some, such as curtain walls and arrowslits, were commonplace., Haakon V Magnusson (10 April 1270 - 8 May 1319) (Old Norse: "Hákon Magnússon"; Norwegian: "Håkon Magnusson") was king of Norway from 1299 until 1319., Bohuslän is a Swedish province in Götaland, on the northernmost part of the country's west coast. It is bordered by Dalsland to the northeast, Västergötland to the southeast, the Skagerrak arm of the North Sea to the west, and the county of Østfold, in Norway, to the north., Greenland  is an autonomous constituent country within the Danish Realm between the Arctic and Atlantic Oceans, east of the Canadian Arctic Archipelago. Though physiographically a part of the continent of North America, Greenland has been politically and culturally associated with Europe (specifically Norway and Denmark, the colonial powers, as well as the nearby island of Iceland) for more than a millennium. The majority of its residents are Inuit, whose ancestors migrated began migrating from the Canadian mainland in the 13th century, gradually settling across the island., Oslo is the capital and the most populous city in Norway. It constitutes both a county and a municipality. Founded in the year 1040, and established as a "kaupstad" or trading place in 1048 by Harald Hardrada, the city was elevated to a bishopric in 1070 and a capital under Haakon V of Norway around 1300. Personal unions with Denmark from 1397 to 1523 and again from 1536 to 1814 and with Sweden from 1814 to 1905 reduced its influence. After being destroyed by a fire in 1624, the city was moved closer to Akershus Fortress during the reign of Christian IV of Denmark and renamed Christiania in his honour. It was established as a municipality ("formannskapsdistrikt") on 1 January 1838. Following a spelling reform, it was known as Kristiania from 1877 to 1925, at which time its original Norwegian name was restored., Härjedalen is a historical province or "landskap" in the centre of Sweden. It borders the country of Norway as well as the provinces of Dalarna, Hälsingland, Medelpad, and Jämtland. The province originally belonged to Norway, but was ceded to Sweden in the Treaty of Brömsebro, 1645., Shetland , also called the Shetland Islands, is a subarctic archipelago that lies northeast of the island of Great Britain and forms part of Scotland, United Kingdom., A correctional facility, detention center, gaol (Australia, New Zealand, Republic of Ireland, UK), jail (US, Canada), penitentiary, prison, or remand centre is a facility in which inmates are forcibly confined and denied a variety of freedoms under the authority of the state as a form of punishment after being convicted of crimes. Prisons are most commonly used within a criminal justice system: people charged with crimes may be imprisoned until they are brought to trial; those pleading or being found guilty of crimes at trial may be sentenced to a specified period of imprisonment. Besides their use for punishing civil crimes, jails and prisons are frequently used by authoritarian regimes., The Scandinavian Peninsula (;  "Skandinavsky poluostrov") is a peninsula in Northern Europe, which generally comprises the mainland of Sweden, the mainland of Norway (with the exception of a small coastal area bordering Russia), the northwestern area of Finland, as well as a narrow area in the west of the Pechengsky District of Russia., Akershus is a county in Norway, bordering Hedmark, Oppland, Buskerud, Oslo, and Østfold; it also has a short border with Sweden (Värmland).

The county administration is in Oslo, which is not part of the county "per se"., Queen Maud Land is a c. 2.7 million-square-kilometre (1 million sq mi) region of Antarctica claimed as a dependent territory by Norway. The territory lies between 20° west and 45° east, between the British Antarctic Territory to the west and the Australian Antarctic Territory to the east. On most maps there had been an unclaimed area between Queen Maud Land's borders of 1939 and the South Pole until June 12, 2015 when Norway formally annexed that area. Positioned in East Antarctica, the territory comprises about one-fifth of the total area of Antarctica. The claim is named after the Norwegian queen Maud of Wales (18691938)., Norway (; Norwegian: (Bokmål) or (Nynorsk); Sami: "Norgga"), officially the Kingdom of Norway, is a sovereign and unitary monarchy whose territory comprises the western portion of the Scandinavian Peninsula plus the island Jan Mayen and the archipelago of Svalbard. The Antarctic Peter I Island and the sub-Antarctic Bouvet Island are dependent territories and thus not considered part of the Kingdom. Norway also lays claim to a section of Antarctica known as Queen Maud Land. Until 1814, the Kingdom included the Faroe Islands (since 1035), Greenland (1261), and Iceland (1262). It also included Shetland and Orkney until 1468. It also included the following provinces, now in Sweden: Jämtland, Härjedalen and Bohuslän., The Republic of Iceland, "Lýðveldið Ísland" in Icelandic, is a Nordic island country in the North Atlantic Ocean. It has a population of and an area of , making it the most sparsely populated country in Europe. The capital and largest city is Reykjavík. Reykjavík and the surrounding areas in the southwest of the country are home to over two-thirds of the population. Iceland is volcanically and geologically active. The interior consists of a plateau characterised by sand and lava fields, mountains and glaciers, while many glacial rivers flow to the sea through the lowlands. Iceland is warmed by the Gulf Stream and has a temperate climate, despite a high latitude just outside the Arctic Circle. Its high latitude and marine influence still keeps summers chilly, with most of the archipelago having a tundra climate., JUSTICE is a human rights and law reform organisation based in the United Kingdom. It is the British section of the International Commission of Jurists, the international human rights organisation of lawyers devoted to the legal protection of human rights worldwide.

His 59-year reign is the longest of Danish monarchs, and of Scandinavian monarchies., Bokmål (literally "book tongue") is an official written standard for the Norwegian language, alongside Nynorsk. Bokmål is the preferred written standard of Norwegian for 85% to 90% of the population in Norway, and is most used by people who speak Standard Østnorsk., A monarchy is a form of government in which a group, usually a family called the dynasty, embodies the country's national identity and one of its members, called the monarch, exercises a role of sovereignty. The actual power of the monarch may vary from purely symbolic (crowned republic), to partial and restricted ("constitutional" monarchy), to completely autocratic ("absolute" monarchy). Traditionally and in most cases, the monarch's post is inherited and lasts until death or abdication, but there are also elective monarchies where the monarch is elected. Each of these has variations: in some elected monarchies only those of certain pedigrees are, whereas many hereditary monarchies impose requirements regarding the religion, age, gender, mental capacity, and other factors. Occasionally this might create a situation of rival claimants whose legitimacy is subject to effective election. Finally, there have been cases where the term of a monarch's reign is either fixed in years or continues until certain goals are achieved: an invasion being repulsed, for instance. Thus there are widely divergent structures and traditions defining monarchy.
Monarchy was the most common form of government until the 19th century, but it is no longer prevalent. Where it exists, it is now usually a constitutional monarchy, in which the monarch retains a unique legal and ceremonial role, but exercises limited or no official political power: under the written or unwritten constitution, others have governing authority. Currently, 47 sovereign nations in the world have monarchs acting as heads of state, 19 of which are Commonwealth realms that recognise Queen Elizabeth II as their head of state. All European monarchies are constitutional ones, with the exception of the Vatican City which is an elective monarchy, but sovereigns in the smaller states exercise greater political influence than in the larger. The monarchs of Cambodia, Japan, and Malaysia "reign, but do not rule" although there is considerable variation in the degree of authority they wield. Although they reign under constitutions, the monarchs of Brunei, Morocco, Oman, Qatar, Saudi Arabia and Swaziland appear to continue to exercise more political influence than any other single source of authority in their nations, either by constitutional mandate or by tradition., Sweden, officially the Kingdom of Sweden (Swedish: ), is a Scandinavian country in Northern Europe. It borders Norway to the west and Finland to the east, and is connected to Denmark in the southwest by a bridge-tunnel across the Öresund. At , Sweden is the third-largest country in the European Union by area, with a total population of 10.0 million. Sweden consequently has a low population density of , with the highest concentration in the southern half of the country. Approximately 85% of the population lives in urban areas., Bouvet Island (Norwegian: Bouvetøya, previously spelled Bouvet-øya) is an uninhabited subantarctic high island and dependency of Norway located in the South Atlantic Ocean at .

It is claimed as a dependency of Norway, and along with Queen Maud Land and Bouvet Island comprises one of the three Norwegian dependent territories in the Antarctic and Subantarctic. Peter I Island is long and , slightly larger than Staten Island. The tallest peak is the ultra and tall Lars Christensen Peak. Nearly all of the island is covered by a glacier and it is surrounded most of the year by pack ice, making it inaccessible almost all year round. There is little life on the island apart from seabirds and seals., Svalbard (formerly known by its Dutch name Spitsbergen) is a Norwegian archipelago in the Arctic Ocean. Situated north of mainland Europe, it is about midway between continental Norway and the North Pole. The islands of the group range from 74° to 81° north latitude, and from 10° to 35° east longitude. The largest island is Spitsbergen, followed by Nordaustlandet and Edgeøya., An archipelago, sometimes called an island group or island chain, is a chain, cluster or collection of islands. The word "archipelago" is derived from the Greek "-  arkhi-" ("chief") and "  pélagos" ("sea") through the Italian "arcipelago". In Italian, possibly following a tradition of antiquity, the Archipelago (from medieval Greek "*" and Latin "archipelagus") was the proper name for the Aegean Sea and, later, usage shifted to refer to the Aegean Islands (since the sea is remarkable for its large number of islands). It is now used to refer to any island group or, sometimes, to a sea containing a small number of scattered islands., Jämtland (Norwegian: "Jemtland"; Latin: "Iemptia") or Jamtland is a historical province ("landskap") in the center of Sweden in northern Europe. It borders to Härjedalen and Medelpad in the south, Ångermanland in the east, Lapland in the north and Trøndelag and Norway in the west.

It has a population of 112,717, the majority of whom live in "Storsjöbygden", the area surrounding lake Storsjön. Östersund is Jämtland's only city and is the 24th most populous city in Sweden., Jan Mayen is a volcanic island in the Arctic Ocean and a part of Norway. It is long (southwest-northeast) and in area, partly covered by glaciers (an area of around the Beerenberg volcano). It has two parts: larger northeast Nord-Jan and smaller Sør-Jan, linked by a wide isthmus. It lies northeast of Iceland (495 km (305 mi) NE of Kolbeinsey), east of central Greenland and west of the North Cape, Norway. The island is mountainous, the highest summit being the Beerenberg volcano in the north. The isthmus is the location of the two largest lakes of the island, Sørlaguna (South Lagoon), and Nordlaguna (North Lagoon). A third lake is called Ullerenglaguna (Ullereng Lagoon). Jan Mayen was formed by the Jan Mayen hotspot., Australia, officially the Commonwealth of Australia, is a country comprising the mainland of the Australian continent, the island of Tasmania and numerous smaller islands.

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., Nynorsk, literally New Norwegian or New Norse, is one of the two written standards of the Norwegian language, the other being Bokmål. From 1885, when the parliament declared them official and equal, until new voting in 1929, their names were Landsmål and Riksmål. The Landsmål language standard was constructed by the Norwegian linguist Ivar Aasen during the mid-19th century, to provide a Norwegian-based alternative to Danish, which was commonly written, and to some extent spoken, in Norway at the time. The official standard of Nynorsk has since been significantly altered. A minor purist fraction of the Nynorsk populace has stayed firm with the Aasen norm, which is known as Høgnorsk (analogous to High German)., The Faroe Islands (Irish: "Na Scigirí") are an archipelago between the Norwegian Sea and the North Atlantic approximately halfway between Norway and Iceland, north-northwest of mainland Scotland.
