Copenhagen Opera House, Denmark

The Copenhagen Opera House is the national opera house of Denmark, and among the most modern opera houses in the world. It is also one of the most expensive opera houses ever built at a cost of 370,000,000 USD. Denmark's national opera is a landmark in Copenhagen and a symbol of the city's rich cultural life. The Copenhagen Opera House is designed by Danish architect Henning Larsen, and a number of Danish artists have contributed to the decor, among them Per Kirkeby who has created four bronze reliefs, and Danish-Icelandic artist Olafur Eliasson who has contributed the three light sculptures for the foyer.

The Opera House is clad with southern German Jura Gelb limestone, and the foyer features Sicilian Perlatino marble. The wall of the auditorium facing the foyer is clad with maple wood, and the ceiling in the main auditorium is adorned with 105,000 sheets of 24 carat gold leaf, equivalent to 1.5 kilos of gold.

The Opera has 6 main stages: 1 visible for the audience, and 5 for rehearsals and set preparation. It has almost everything needed for opera, ballet etc., including stage elevators, movable ballet floors, etc. The building totals 41,000 m² and has 14 floors, of which 5 are below ground. It contains more than 1000 rooms, including a large orchestral rehearsal room. Besides the main stage, the building also includes a small stage for experimental theatre, a so-called "black box" theatre called Takkelloftet.
