Oslo

The municipality of Oslo has a population of 724,290 as of 1 January 2025. The urban area extends far beyond the boundaries of the municipality into the surrounding county of Akershus (municipalities of Asker, Bærum, Lillestrøm, Enebakk, Rælingen, Lørenskog, Nittedal, Gjerdrum, Nordre Follo); being, to a great degree suburbs of Oslo making up approximately 500,000 of the population of the greater Oslo region. The total population of this agglomeration was 1,546,706 in 2023. The city of Oslo was established as a municipality on 3 January 1838 (see formannskapsdistrikt). It was separated from the county of Akershus to become a county of its own in 1842. The rural municipality of Aker was merged with Oslo on 1 January 1948 (and simultaneously transferred from Akershus county to Oslo county). Furthermore, Oslo shares several important functions with Akershus county. In addition is Marka (1,610 residents, 301.1 km2), that is administered by several boroughs; and Sentrum (1,471 residents, 1.8 km2) that is partially administered by St. Hanshaugen, and in part directly by the city council. As of 27 February 2020, there were 2,386 residents who were not allocated to a borough. The nine municipalities directly included in the Urban area of Oslo. ==Name and seal==

After being destroyed by a fire in 1624, during the reign of King Christian IV, a new city was built closer to Akershus Fortress and named Christiania in the king's honour. The old site east of the Aker river was not abandoned, however, and the village of Oslo remained as a suburb outside the city gates. The suburb called Oslo was eventually included in the city proper. In 1925 the name of the suburb was transferred to the whole city, while the suburb was renamed "Gamlebyen", literally "the Old town", to avoid confusion. The Old Town is an area within the administrative district Gamle Oslo. The previous names are reflected in street names like Oslo gate (Oslo street) and Oslo hospital. Toponymy The origin of the name Oslo has been the subject of much debate. It is almost certainly derived from Old Norse and was—in all probability—originally the name of a large farm at Bjørvika, while the meaning of that name is disputed. Modern linguists generally interpret the original Óslo, Áslo or Ánslo as either "meadow at the foot of a hill" or "meadow consecrated to the Gods", with both considered equally likely. Erroneously, it was once assumed that Oslo meant "the mouth of the Lo river", a supposed previous name for the river Alna. Not only has no evidence been found of a river "Lo" predating the work where Peder Claussøn Friis first proposed this etymology, but the very name is ungrammatical in Norwegian: the correct form would have been Loaros (cf. Nidaros). The name Lo is now believed to be a back-formation arrived at by Friis in support of his [idea about] etymology for Oslo. Seal Oslo is one of very few cities in Norway, besides Bergen and Tønsberg, that does not have a formal coat of arms, but which uses a city seal instead. The seal of Oslo shows the city's patron saint, St. Hallvard, with his attributes, the millstone and arrows, with a naked woman at his feet. He is seated on a throne with lion decorations, which at the time was also commonly used by the Norwegian kings. Other names Oslo has various nicknames and names in other languages. The city is sometimes known as "The Tiger City" (), probably inspired by an 1870 poem by Bjørnstjerne Bjørnson which referenced then-Christiania in central Oslo. The nickname is mostly used by Norwegians from out of town, and rarely by people from the Oslo region. ==History==

Viking Age During the Viking Age, the area that includes modern Oslo was located in Viken, the northernmost province of Denmark. Control over the area shifted between Danish and Norwegian kings in the Middle Ages, and Denmark continued to claim the area until 1241. According to the Norse sagas, Oslo was founded around 1049 by Harald Hardrada. Recent archaeological research, however, uncovered Christian burials which could be dated to prior to AD 1000, evidence of a preceding urban settlement. This called for the celebration of Oslo's millennium in 2000 rather than 2049. 1000–1600 Under the reign of Olaf III of Norway (1067–1093), Oslo became a cultural centre for Eastern Norway. Hallvard Vebjørnsson became the city's patron saint and is depicted on the city's seal. In 1174, Hovedøya Abbey was built. The churches and abbeys became major owners of large tracts of land, which proved important for the city's economic development, especially before the Black Death. At the end of the 12th century, Hanseatic League traders from Rostock moved into the city and gained major influence in the city. On 25 July 1197, Sverre of Norway and his soldiers attacked Oslo from Hovedøya. During the Middle Ages, Oslo reached new heights during the reign of Haakon V of Norway (1299–1319). He was the first king to reside permanently in the city, and it has been regarded as the capital city of Norway since his reign. He also started the construction of the Akershus Fortress and the Oslo Kongsgård. The Black Death came to Norway in 1349 and, like other cities in Europe, the city suffered greatly. The churches' earnings from their land dropped so much that the Hanseatic traders dominated the city's foreign trade in the 15th century. In 1380, Norway was the weaker part in a personal union with Denmark, and Oslo's role was reduced to that of provincial administrative centre, with the monarchs residing in Copenhagen. 17th century Over the years, fires destroyed significant parts of the city multiple times, as many of the city's buildings were built entirely of wood. After the fourteenth calamity, in 1624, which lasted for three days, Christian IV of Denmark decided that the old city should not be rebuilt again. His men built a network of roads on the other side of the bay in Akershagen near Akershus Castle. He demanded that all citizens move their shops and workplaces to the newly built city of "Christiania", named in his honour. The part of the city built starting in 1624 is now often called '''' because of its orthogonal layout in regular, square blocks. Anatomigården is a historic timber framing house located on the north side of Christiania Torv; it was built in 1640. The transformation of Christiania went slowly for the first hundred years. However, outside of the city at Vaterland, Grønland, and the old town of Oslo, a new, unmanaged part of the city arose populated by citizens of lower class status. The last Black Death outbreak in Oslo occurred in 1654. 18th century In the 18th century, after the Great Northern War, the city's economy boomed with shipbuilding and trade. The strong economy transformed Christiania into a trading port. 19th century The Royal Frederick University (now the University of Oslo) was founded in 1811; the fact that it was founded this late reportedly had an adverse effect on the development of the nation. In 1814 the former provincial town of Christiania became the capital of the independent Kingdom of Norway, when the union with Denmark was dissolved and replaced by a personal union with Sweden. Several state institutions were established and the city's role as a capital initiated a period of rapidly increasing population. The government of this new state needed buildings for its expanding administration and institutions. Several important buildings and landmarks were erected in the 19th century, including the Royal Palace (1825–1848), the Stock Exchange (1826–1828), the Bank of Norway (1828), the Storting (1861–1866), the National Theatre (1899), and several University buildings. Among the world-famous artists who lived here during this period were Henrik Ibsen and Knut Hamsun (the latter was awarded the Nobel Prize for literature). Large areas of the surrounding Aker municipality were incorporated in 1839, 1859, and 1878. The 1859 expansion included Grünerløkka, Grønland, and Oslo. At that time the area called Oslo (now Gamlebyen or Old Town) was a village or suburb outside the city borders east of Aker river. The population increased from approximately 10.000 in 1814 to 230.000 in 1900. In 1850, Christiania overtook Bergen and became the most populous city in the country. Christiania expanded its industry from 1840, most importantly around Akerselva. There was a spectacular building boom during the last decades of the 19th century, with many new apartment buildings and renewal of the city centre, but the boom collapsed in 1899. In 1877 the city was renamed Kristiania. 1900–present The city and municipality used the name Kristiania until 1 January 1925 when the original name of Oslo was restored. This was because Norway became fully independent in 1905, and Norwegians argued that a name memorializing a Danish king (Christian IV of Denmark) was inappropriate as the name of the capital of their country. The municipality developed new areas such as Ullevål garden city (1918–1926) and Torshov (1917–1925). City Hall was constructed in the former slum area of Vika from 1931 to 1950. In 1948, Oslo merged with Aker, a municipality which surrounded the capital and was 27 times larger, thus creating the modern, vastly enlarged Oslo municipality. At the time, Aker was a mostly affluent, green suburban community, and the merger was unpopular in Aker. Other suburbs, such as Lambertseter, began to be developed in the 1950s. Aker Brygge was constructed on the site of the former shipyard, Akers Mekaniske Verksted, from 1982 to 1998. Norway was invaded by Germany on 9 April 1940. Efforts to stop the invasion, most notably the sinking of the Blücher, delayed the occupation of Oslo for several hours which allowed King Haakon to escape the city. Oslo remained occupied throughout the war until Germany capitulated in 1945. During this time, the occupying troops were harried by saboteurs in acts of resistance. On 31 December 1944, allied bombers missed their intended target and hit a tram, resulting in 79 civilian deaths. During the 2011 Norway attacks, Oslo was hit by a bomb blast that ripped through the Government Quarter, damaging several buildings including the building that houses the Office of the Prime Minister. Eight people died in the bomb attack. On 25 June 2022, two people were killed and 21 others injured in a mass shooting. An Iranian-born Norwegian citizen was subsequently charged with "aggravated terrorism". The city has continued to expand. For a few years, new large scale housing areas and infrastructure projects are being built and planned across the city, notably in Hasle, Helsfyr,Bjørvika, Nydalen and Sinsen, this is increasing the density in and around Ring 2 and Ring 3. The Fornebu line on the metro is under construction as of 2024, and further subway lines crossing the inner city are being planned. ==Geography==

Oslo occupies an arc of land at the northernmost end of the Oslofjord. The fjord, which is nearly bisected by the Nesodden peninsula opposite Oslo, lies to the south; in all other directions Oslo is surrounded by green hills and mountains. There are 40 islands within the city limits, the largest being Malmøya (), and scores more around the Oslofjord. Oslo has 343 lakes, the largest being Maridalsvannet (). This is also a main source of drinking water for large parts of Oslo. Although Eastern Norway has a number of rivers, none of these flow into the ocean at Oslo. Instead Oslo has two smaller rivers: Akerselva (draining Maridalsvannet, which flows into the fjord in Bjørvika), and Alna. The waterfalls in Akerselva gave power to some of the first modern industry of Norway in the 1840s. Later in the century, the river became the symbol of the stable and consistent economic and social divide of the city into an East End and a West End; the labourers' neighbourhoods lie on both sides of the river, and the divide in reality follows Uelands street a bit further west. River Alna flows through Groruddalen, Oslo's major suburb and industrial area. The highest point is Kirkeberget, at . Although the city's population is small compared to most European capitals, it occupies an unusually large land area, of which two-thirds are protected areas of forests, hills and lakes. Its boundaries encompass many parks and open areas, giving it an airy and green appearance. Climate Oslo has a humid continental climate (Köppen climate classification: Dfb) or, if the original Köppen winter threshold is used, an oceanic climate (Cfb) bordering on a humid continental climate in the 1991–2020 base period. Oslo has some of the warmest summers of Norway and fairly cold winters. Oslo receives a fair amount of precipitation during the year. The warmest month on record is July 1901 with mean , and the all-time high was also recorded in July 1901. The warmest month in more recent years is July 2018 with mean and average daily high . The record summer of 2018 also recorded the warmest May and May all-time high with on 30th, and 2018 was even the sunniest year on record with 2133 hours of sunshine. On 27 July 2018, the temperature in Oslo rose to , the hottest recorded since 1937, when weather recordings started at Blindern. In January, on average three out of four days are below freezing () and one out of four days is colder than (1961–1990). The coldest temperature recorded is , on 21 January 1841, while the coldest recorded at Blindern is in January 1941. The coldest temperature more recently was on 6 January 2024, where the temperature reached -23.1 °C (-17 °F) at Oslo-Blindern, which is the coldest measured temperature since January 1987. The coldest month on record is January 1941 and also January 1947 with mean and average daily low . The average date for the last overnight freeze (low below ) in spring is 23 April and average date for first freeze in autumn is 17 October giving a frost-free season of 176 days (1981–2010 average for Blindern). Oslo sits right on the border between hardiness zones 7a and 7b. Oslo Gardermoen airport is located 35 km northeast of Oslo and has a humid continental climate (Köppen climate classification: Dfb) bordering on a subarctic climate (Köppen climate classification: Dfc). ==Parks and recreation areas==

's Vigeland installation in Oslo in Oslo Oslo has many parks and green areas within the city core, as well as outside it. • Frogner Park is a large park located a few minutes' walk away from the city centre. This is the biggest and best-known park in Norway, with a large collection of sculptures by Gustav Vigeland. • Bygdøy is a large green area, commonly called the Museum Peninsula of Oslo. The area is surrounded by the sea and is one of the most expensive districts in Norway. • Ekebergparken Sculpture Park is a sculpture park and a national heritage park with a panoramic view of the city at Ekeberg in the southeast of the city. • St. Hanshaugen Park is an old public park on a high hill in central Oslo. "St. Hanshaugen" is also the name of the surrounding neighbourhood as well as the larger administrative district (borough) that includes major parts of central Oslo. • Tøyen Park stretches out behind the old Munch Museum, and is a vast, grassy expanse. In the north, there is a lookout point known as Ola Narr. The Tøyen area also includes the Botanical Garden and Museum belonging to the University of Oslo. Oslo (with neighbouring Sandvika-Asker) is built in a horseshoe shape on the shores of the Oslofjord and limited in most directions by hills and forests. As a result, any point within the city is relatively close to the forest. There are two major forests bordering the city: Østmarka (literally "Eastern Forest", on the eastern perimeter of the city), and the very large Nordmarka (literally "Northern Forest", stretching from the northern perimeter of the city deep into the hinterland). • Sognsvann is a lake in Oslomarka, located at the land border, just north of Oslo. Sognsvann was drinking water for Oslo from 1876 to 1967. The lake's altitude above sea level is 183 metres. The water is in a popular hiking area. Near the water itself, it is great for barbecues, swimming, beach volleyball and other activities. The municipality operates eight public swimming pools. Tøyenbadet is the largest indoor swimming facility in Oslo and one of the few pools in Norway offering a 50-metre main pool. Another in that size is the outdoor pool Frognerbadet. ==Cityscape==

Oslo's cityscape is being redeveloped as a modern city with various access-points, an extensive metro-system with a new financial district and a cultural city. In 2008, an exhibition was held in London presenting the award-winning Oslo Opera House, the urban regeneration scheme of Oslo's seafront, Munch/Stenersen and the new Deichman Library. Most of the buildings in the city and in neighbouring communities are low in height with only the Plaza, Posthuset and the highrises at Bjørvika considerably taller. Architecture is a large construction project in the seaside of central Oslo, stretching from Bygdøy in the west to Ormøya in the east. Some areas include: Bjørvika, Aker brygge, Tjuvholmen, and the central station area. Oslo's architecture is very diverse. The architect Carl Frederik Stanley (1769–1805), who was educated in Copenhagen, spent some years in Norway around the turn of the 19th century. He undertook some minor commissions for wealthy patrons in and around Oslo, but his major achievement was the renovation of the Oslo Katedralskole, completed in 1800. He added a classical portico to the front of an older structure, and a semicircular auditorium that was sequestered by Parliament in 1814 as a temporary place to assemble, now preserved at Norsk Folkemuseum as a national monument. When Christiania was made capital of Norway in 1814, there were practically no buildings suitable for the many new government institutions. An ambitious building program was initiated, but realised very slowly because of economic constraints. The first major undertaking was the Royal Palace, designed by Hans Linstow and built between 1824 and 1848. Linstow also planned Karl Johans gate, the avenue connecting the Palace and the city, with a monumental square halfway to be surrounded by buildings for University, the Parliament (Storting) and other institutions. Only the university buildings were realised according to this plan. Christian Heinrich Grosch, one of the first architects educated completely within Norway, designed the original building for the Oslo Stock Exchange (1826–1828), the local branch of the Bank of Norway (1828), Christiania Theatre (1836–1837), and the first campus for the University of Oslo (1841–1856). For the university buildings, he sought the assistance of the German architect Karl Friedrich Schinkel. German architectural influence persisted in Norway, and many wooden buildings followed the principles of Neoclassicism. In Oslo, the German architect Alexis de Chateauneuf designed Trefoldighetskirken, the first neo-gothic church, completed by von Hanno in 1858. A number of landmark buildings, particularly in Oslo, were built in the Functionalist style (better known in the US and Britain as Modernist), the first being (1925–1927) by Lars Backer, demolished in 1970. Backer also designed the restaurant at Ekeberg, which opened in 1929. Kunstnernes Hus art gallery by Gudolf Blakstad and Herman Munthe-Kaas (1930) still shows the influence of the preceding classicist trend of the 1920s. The redevelopment of Oslo Airport (by the Aviaplan consortium) at Gardermoen, which opened in 1998, was Norway's largest construction project to date. ==Politics and government==

Oslo is the capital of Norway, and as such is the seat of Norway's national government. Most government offices, including that of the Prime Minister, are gathered at Regjeringskvartalet, a cluster of buildings close to the national Parliament, the Storting. Constituting both a municipality and a county of Norway, the city of Oslo is represented in the Storting by twenty members of parliament. The Conservative Party is the most represented party in Oslo with five members, the Labour Party has four, the Liberals and the Socialist Left Party have three each; the Green Party, the Red Party have two each and the Progress Party has one. The combined municipality and county of Oslo has had a parliamentary system of government since 1986. The supreme authority of the city is the City Council (Bystyret), which has 59 seats. Representatives are popularly elected every four years. The city council has five standing committees, each having its own areas of responsibility. Recent elections The largest parties in the City Council after the 2015-elections were the Labour Party and the Conservatives, with 20 and 19 representatives respectively. After 2015, the city government was a coalition of the Labour Party, the Green Party and the Socialist Left. With support from the Red Party, the coalition maintained a workable majority in the city council. Following the local elections of 2019, the centre-left coalition remained in government until the 2023 local elections. 2023 elections After the Conservative Party's substantial gains in the 2023 election, they formed an alliance with the Liberal Party. With confidence and support from the Christian Democrats and the Progress Party, this alliance was able to form a government. The Governing Mayor of Oslo is the head of the City government. The post was created with the implementation of parliamentarism in Oslo and is similar to the role of the prime minister at the national level. The governing mayor is Eirik Lae Solberg. ==Economy==

, part of the redesign of former dock and industrial land in Oslo known as the Barcode Project Oslo has a varied and strong economy and was ranked number one among European large cities in economic potential in the fDi Magazine report European Cities of the Future 2012. Det Norske Veritas, headquartered at Høvik outside Oslo, is one of the three major maritime classification societies in the world, with 16.5% of the world fleet to class in its register. The city's port is the largest general cargo port in the country and its leading passenger gateway. Close to 6,000 ships dock at the Port of Oslo annually with a total of 6 million tonnes of cargo and over five million passengers. The GDP of Oslo totaled €64 billion (€96,000 per capita) in 2016, which amounted to 20% of the national GDP. This compares with NOK253 billion (€23 billion) in 1995 (adjusting for 2016 inflation). The metropolitan area, bar Moss and Drammen, contributed 25% of the national GDP in 2003 and was also responsible for more than one quarter of tax revenues. In comparison, total tax revenues from the oil and gas industry on the Norwegian Continental Shelf amounted to about 16%. Oslo is one of the most expensive cities in the world. , it is ranked tenth according to the Worldwide Cost of Living Survey provided by Mercer Human Resource Consulting and first according to the Economist Intelligence Unit (EIU). of the EIU's Worldwide Cost of Living survey, Oslo now ranks as the third most expensive city in the world. Although Oslo does have the most expensive housing market in Norway, it is comparably cheaper than other cities on the list in that regard. Meanwhile, prices on goods and services remain some of the highest of any city. Oslo hosts 2654 of the largest companies in Norway. Within the ranking of Europe's largest cities ordered by their number of companies Oslo is in fifth position. A whole group of oil and gas companies is situated in Oslo. According to a report compiled by Swiss bank UBS in the month of August 2006, Oslo and London were the world's most expensive cities. ==Environment and decarbonization==

Oslo is a compact city. It is easy to move around by public transportation and rentable city bikes accessible to all in many places in the city centre. In 2003, Oslo received The European Sustainable City Award and in 2007 Reader's Digest ranked Oslo as number two on a list of the world's greenest, most livable cities. In 2019 Oslo was selected as the European Green Capital. The City of Oslo has set the goal of becoming a low carbon city, and reducing greenhouse gas emissions 95% from 1990 levels by 2030. To reach this goal, in 2017, under the leadership of the Green Party, Oslo became the first city in the world to implement a climate budget. This tool makes each individual department and agency of the local government responsible for counting their emissions and cut them according the budget. The progress has to be reported together with the economical budget reports, three times a year. The C40 Cities Climate Leadership Group later adopted having a climate budget by 2030 as one of their criteria for membership. By October 2022, Oslo had an extensive network of bicycle lanes and tram lines, most of its ferry boats had been electrified, and the city was "on course to become the first capital city in the world with an all-electric public transport system", including electric buses. The climate action plan for the Port of Oslo includes implementing a low-carbon contracting process, and installing shore power for vessels which are docked. ==Education==

The greater Oslo region has several higher educational institutions and is home to more than 73,000 students. The University of Oslo is the largest institution for higher education in Norway with 27,400 students and 7,028 employees in total. ==Culture==

, an 1824 tea pavilion and art gallery in Frogner Park Oslo has a large and varied number of cultural attractions, which include several buildings containing artwork from Edvard Munch and various other international artists but also several Norwegian artists. Several world-famous writers have either lived or been born in Oslo. Examples are Knut Hamsun and Henrik Ibsen. The government has recently invested large amounts of money in cultural installations, facilities, buildings and festivals in the City of Oslo. Bygdøy, outside the city centre, is the centre for history and the Norwegian Vikings' history. The area contains many parks and seasites and many museums. Examples are the Fram Museum, Vikingskiphuset and the Kon-Tiki Museum. Oslo hosts the annual Oslo Freedom Forum, a conference described by The Economist as "on its way to becoming a human-rights equivalent of the Davos economic forum." Oslo is also known for giving out the Nobel Peace Prize every year. Food Grønland, the central areas around Youngstorget and Torggata, Karl Johans gate (the main pedestrian thoroughfare), Aker Brygge and Tjuvholmen, Sørenga, and the boroughs of Frogner, Majorstuen, St. Hanshaugen / Bislett, and Grünerløkka all have a high concentration of cafes and restaurants. There are several food markets, the largest being Mathallen Food Hall at Vulkan with more than 30 specialty shops, cafés, and eateries. As of March 2018, six Oslo restaurants were mentioned in the Michelin Guide. Maaemo is the only Norwegian restaurant ever to have been awarded three Michelin stars. Statholdergaarden, Kontrast, and Galt each have one star. Only two restaurants in Oslo have a BIB gourmand mention: Restaurant Eik and Smalhans. Due to its proximity to the North Sea, fish and seafood are a staple component of cuisine in Oslo. Many restaurants also serve game meat year round. Museums, galleries Oslo houses several major museums and galleries. The Munch Museum contains The Scream and other works by Edvard Munch, who donated all his work to the city after his death. The city council is planning a new Munch Museum which is most likely to be built in Bjørvika, in the southeast of the city. The museum will be named Munch/Stenersen. Folkemuseet is located on the Bygdøy peninsula and is dedicated to Folk art, Folk Dress, Sami culture and the viking culture. The outdoor museum contains 155 authentic old buildings from all parts of Norway, including a Stave Church. The Vigeland Museum located in the large Frogner Park, is free to access and contains over 212 sculptures by Gustav Vigeland including an obelisk and the Wheel of Life. Another popular sculpture is Sinnataggen, a baby boy stamping his foot in fury. This statue is very well known as an icon in the city. There is also a newer landscaped sculpture park, Ekebergparken Sculpture Park, with works by Norwegian and international artists such as Salvador Dalí. The Viking Ship Museum features three Viking ships found at Oseberg, Gokstad and Tune and several other unique items from the Viking Age. The museum is currently closed for renovation, but will open again in 2026. The new museum will be called Museum of the Viking Age, and has plans to feature more viking items than at the old location. The Oslo City Museum holds a permanent exhibition about the people in Oslo and the history of the city. The Kon-Tiki Museum houses Thor Heyerdahl's Kon-tiki and Ra II. The Fram Museum features items from arctic and antarctic expeditions, including the wooden ship Fram used by Fritjof Nansen and Roald Amundsen during their expeditions. The National Museum holds and preserves, exhibits and promotes public knowledge about Norway's most extensive collection of art. The museum shows permanent exhibitions of works from its own collections but also temporary exhibitions that incorporate work loaned from elsewhere. The Nobel Peace Center is an independent organisation opened on 11 June 2005 by the King Harald V as part of the celebrations to mark Norway's centenary as an independent country. The building houses a permanent exhibition, expanding every year when a new Nobel Peace Prize winner is announced, containing information of every winner in history. The building is mainly used as a communication centre. Oslo's biggest rock festival is Øyafestivalen or simply "Øya". It draws about 60,000 people to the Tøyen Park east in Oslo and lasts for four days. The Oslo International Church Music Festival has been held annually since 2000. The Oslo World Music Festival showcases people who are stars in their own country but strangers in Norway.

The Norwegian Wood Rock Festival is held every year in June in Oslo. The Nobel Peace Prize Ceremony is headed by the Institute; the award ceremony is held annually in The City Hall on 10 December. Even though Sami land is far away from the capital, the Norwegian Museum of Cultural History marks the Sami National Day with a series of activities and entertainment. The World Cup Biathlon in Holmenkollen is held every year and here male and female competitors compete against each other in Sprint, Pursuit and Mass Start disciplines. Other examples of annual events in Oslo are Desucon, a convention focusing on Japanese culture and Færderseilasen, the world's largest overnight regatta with more than 1100 boats taking part every year. Rikard Nordraak, composer of the national anthem of Norway, was born in Oslo in 1842. Norway's principal orchestra is the Oslo Philharmonic, based at the Oslo Concert Hall since 1977. Although it was founded in 1919, the Oslo Philharmonic can trace its roots to the founding of the Christiania Musikerforening (Christiania Musicians Society) by Edvard Grieg and Johan Svendsen in 1879. Oslo has hosted the Eurovision Song Contest twice, in 1996 and 2010. Performing arts Oslo houses over 20 theatres, such as the Norwegian Theatre and the National Theatre located at Karl Johan Street.
