This architectural marvel is only a short stroll from Oslo’s Central Station (Oslo S). I was amazed at the way this work of art blended in so seamlessly with the water. The Norwegian National Opera and Ballet both call this amazing building home, and many performances and shows are held here when touring Norway. The exterior is build from Italian marble and white granite which makes it sparkle in the night like a modern floating iceberg of Oslo’s fjord. The coolest part of the Oslo Opera House is that visitors can walk on the roof of the building! I highly recommend doing this at night as well for a beautiful view of the city. The Oslo Pass will get you a 20% discount on a tour of the Opera House (Adult Admission: NOK 100, £10, $17), but you can climb and walk around free of charge.
