Oslo's new Opera House, completed in 2007

Massive, astonishing, brilliant

A massive building in white granite and Carrara marble, by the side of (and partly in) the Oslo Fjord.

Its sloping roof is also there for enjoyment : you can walk up it and enjoy panoramic views of the city.  The main auditorium seats 1,364; the building contains 1,100 rooms in a total area of 38,500 square metres.
