"If there were ever a three-dimensional ode to Nordic design, the impressive Oslo Opera House would be it. On the waterfront in the Bjørvika neighborhood with the Oslo fjord as a backdrop, the otherworldly building is home to the Norwegian National Opera and Ballet, and the National Opera Theater. Its angular profile suggests an iceberg and an inclined flat roof extends the theater’s public space down to earth, so that visitors can access the roof, the slope and the plaza in front."
