Oslo Opera House

A striking white marble and glass building that seems to rise out of the Oslofjord, home of the Norwegian National Opera and Ballet, opened in 2008. You can walk up its sloping roof for views over the city and the fjord, free at any time.

Inside, the oak-lined auditorium can be seen on guided tours, or at a performance. Next door, the Munch Museum's tall building holds the world's largest collection of Edvard Munch's works. The new Deichman library and the sauna rafts in the harbour are nearby.
