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 stein eberg 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.
