"Olso’s Opera House — which opened in 2007 — has become one of the city’s most iconic modern landmarks. Sitting on the city’s harbor, the building was designed by Norwegian architecture studio Snøhetta and went on to win awards at the World Architecture Festival and the European Union Prize for Contemporary Architecture. If you want to explore the architecture, and the wider city, the Opera House’s roof is open to the public and offers a range of views across Oslo."
