Oslo City Hall (Norwegian: Oslo rådhus) houses the city council, city administration, and art studios and galleries. The construction started in 1931, but was paused by the outbreak of World War II, before the official inauguration in 1950. Its characteristic architecture, artworks and the Nobel Peace Prize ceremony, held on 10 December, makes it one of Oslo's most famous buildings. It was designed by Arnstein Arneberg and Magnus Poulsson. The roof of the eastern tower has a 49-bell carillon which plays every hour. It is situated in Pipervika in central downtown Oslo. The area was completely renovated and rebuilt to make room for the new city hall, back in the late 1920s. In June 2005 it was named Oslo's "Structure of the Century", with 30.4% of the votes.
In early Middle Ages, it looks like different halls in Oslo had the City Hall status from time to time. Right where Oslo Market is located today, the Early Oslo City Hall was built. From the sources we know that the old Oslo City Hall had an open wine cellar for public use. Norwegian Medieval historian Tore Vigerus says the following is in his book, Norske Rigs-Registranter III:
Oslo (English pronunciation: /ˈɒzloʊ/, OZ-loh,Norwegian pronunciation: [ˈuʂˈlu] ( listen) or, rarer [ˈusˈlu] or [ˈuʂlu]) is the capital and the most populous city in Norway.
Oslo constitutes both a county and a municipality. Founded in the year 1040, and established as a "kaupstad" or trading place in 1048 by King Harald III, the city was elevated to a bishopric in 1070 and a capital under Haakon V 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 King Christian IV 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.
Oslo is the 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 among 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 Central Station (Norwegian: Oslo sentralstasjon, abbreviated Oslo S) is the main railway station in Oslo, and the largest railway station within the entire Norwegian railway system. It is the terminus of Drammen Line, Gardermoen Line, Gjøvik Line, Hoved Line and Østfold Line. It serves express, regional and local rail services by four companies. The railway station is owned and operated by Norwegian National Rail Administration and was opened in 1980.
Oslo Central was built on the site of the older Oslo East Station (Oslo Østbanestasjon, Oslo Ø), the combining of the former east and west stations being made possible by the opening of the Oslo Tunnel. Oslo Central has nineteen tracks, thirteen of which have connections through the Oslo Tunnel. The station has two buildings, the original Oslo East building and the newer main building for Oslo Central. Each building houses a large shopping centre. The square in front of the station is called Jernbanetorget.
