A spellbinding landmark right on the harbour, the home of the Norwegian National Opera & Ballet is the Oslo Opera House, completed in 2007. Resembling an iceberg, this angular building is clad with white granite and Italian Carrara marble and has a main auditorium that can seat 1,364 spectators.

On a casual visit you can go up to the roof for free for a phenomenal view of the Oslofjord, best done at sunset.

The inside is also a delight, with warm surfaces covered with oak to counter the iciness of the exterior’s glass and stone.
