Rådhusplassen

thumb|Part of the square in front of Oslo City Hall. Rådhusplassen ("The City Hall Square") is a square located between Oslo City Hall and the Oslofjord in Vika, Oslo, Norway. Previously used as a road and part of European route E18, it has since 1994 served as a recreational area. North of the square stands the city hall, to the south the fjord, to the east Akershus Fortress and to the east the former Western Railway Station.

==History== Up until the 1920s, the area of Pipervika was dominated by common housing, and was seen by the contemporary elite as an area with low housing standard, poor hygiene and lack of moral standards. Plans for the new city hall started in 1915, and in 1921 the Parliament of Norway passed legislation allowing expropriation of parts of Pipervika to build a city hall and a square. An architectural competition announced in 1916 was won by the architects Arnstein Arneberg and Magnus Poulsson. Their plan involved paving the square with granite, and making it an urban open space, instead of a park.
