The Opera House was a gift to Copenhagen from the A.P. Møller Foundation and opened in 2005. The building has 14 floors, 5 of which are underground. 

The two cranes to the left of the building remain as some of the last signs of the shipyard's heyday in Copenhagen and are believed to have been the inspiration for the Opera's roof. Talking about the roof, it has been given a nickname as the "toaster" and it stretches 32 meters out into open space. Every summer Redbull Cliff Divers Jump from the roof of the Opera House which you can watch both from land and by boat.

Some call the large stage (which can be seen through the glass facade out towards the harbor) the pumpkin, due to its round shape and orange color. Some believe the pumpkin symbolize the fairytale of Cinderella where a pumpkin is enchanted into a beautiful carriage, in the same way the opera enchants their audience. 

There are a total of 1000 rooms in the whole building. Including two stages where there are over 2000 audience seats.
