Henning Larsen designed this building in collaboration with Mærsk Mc-Kinney Møller. One of Larsen’s focuses was the glass front of the building and he wanted to keep the integrity of the initial plan. This is the national opera house of Denmark, and one of the most expensive opera houses ever built. The building is faced with limestone and surrounded by canals in order to create the impression that the opera house is on an island. The floor in the foyer is Sicilian marble. This is a beautiful architectural feat that juxtaposes modern look of the outside with the decadence of marble and gold leaf inside.
