Oslo

Oslo, is a municipality, and the capital and most populous city of Norway. As a municipality (formannskapsdistrikt), it was established on 1 January 1838. Founded around 1048 by King Harald III, the city was largely destroyed by fire in 1624. The city was moved during the reign of King Christian IV. It was rebuilt closer to Akershus Castle, and renamed Christiania in his honour (also spelled Kristiania in the late 1800s). In 1925, twenty years after the dissolution of personal union between Norway and Sweden, the city reclaimed its original Norwegian name, Oslo. The diocese of Oslo is one of the five original dioceses in Norway, which originated around the year 1070.
Oslo is the cultural, scientific, economic and governmental centre of Norway. The city is also a hub of Norwegian trade, banking, industry and shipping. It is an important centre for maritime industries and maritime trade in Europe. The city is home to many companies within the maritime sector, some of which are amongst the world's largest shipping companies, shipbrokers and maritime insurance brokers. Oslo is a pilot city of the Council of Europe and the European Commission intercultural cities programme.
Oslo is considered a global city and ranked "Beta World City" in studies performed by the Globalization and World Cities Study Group and Network in 2008. It was ranked number one in terms of quality of life among European large cities in the European Cities of the Future 2012 report by fDi Magazine. For several years, Oslo has been listed as one of the most expensive cities in the world along with such other global cities, as Zurich, Geneva, Copenhagen, Paris, and Tokyo. In 2009, however, Oslo regained its status as the world's most expensive city. A survey conducted by ECA International in 2011 placed Oslo 2nd after Tokyo.
As of 2010 the metropolitan area of Oslo has a population of 1,442,318, of whom 912,04 live in the contiguous conurbation. The population currently increases at record rates, making it the fastest growing city in Europe. This growth stems for the most part from immigration and high birth rates among immigrants, but also from intra-national migration. The Norwegian population in the city is not decreasing in absolute numbers, but in relative terms the pecentage of native Norwegians of the total population in the city proper is decreasing due to a growing immigrant population and thus a growing total population.  The immigrant share of the population in the city proper now counts more than 25% of the city's total.


 Parks and open spaces in Oslo


Oslo has a large number of 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 most reputed park in Norway with a large collection of sculptures of Gustav Vigeland
Bygdøy is a huge and green area, commonly called the Museum Peninsula of Oslo. The beautiful location, surrounded by the sea, makes it the most expensive Norwegian district.
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 Munch Museum, and is a vast, grassy expanse. In the north, there is a viewing 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).
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. The outdoor pool Frognerbadet also has the 50-metre range.

Norway's principal orchestra is the Oslo Philharmonic, based at the Oslo Concert Hall since 1977.
