A spellbinding landmark right on the harbor, 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. In the lobby, there’s a wall panel designed by Olafur Eliasson, and on a platform in the fjord is a glass and stainless steel sculpture by Monica Bonvicini.
