Operataket

Kirsten Flagstads plass 1, 0150 Oslo

The Opera House in Bjørvika is built so you can walk straight up onto the roof - the sloping marble surfaces rise from the ground to the top, and it's free. Children love running up and down the slopes, and from the top you have a wide view over the fjord, the city and the boats. Bring good shoes; the marble can be slippery when wet.
