The Copenhagen Opera House is the national theater of Denmark, and one of the most modern opera theaters in the world. It is also one of the most expensive opera theaters ever built with construction costs of over $ 500 million. It is located on Holmen Island, in the center of Copenhagen. The Opera House was donated to the Danish State by the A.P. Møller and Chastine Mc-Kinney Møller in August 2000 (A.P. Møller was co-founder of today's company known as Mærsk). Some politicians have been offended by the private donation, partly because the totality of the cost of the project would be tax deductible, thus virtually forcing the government to buy the building, but was accepted by Parliament and the government in the fall of 2000. It was designed by architect Henning Larsen and engineering studios Ramboll and Buro Happold and Theatreplan Theater Consultants. The acoustics have been designed by the Auro Acoustics. A.P. Møller had the last word in the design of the building, including the addition of steel to the front windows. Construction began in June 2001 and ended on 1 October 2004. It was inaugurated on January 15, 2005 with the presence of Mærsk Mc-Kinney Møller, Danish Prime Minister Anders Fogh Rasmussen, and Queen Margherita II. The Opera is right in front of the Amalienborg Palace, along the shore of the harbor. The theater is built in alignment with Amalienborg and the Church of the Marbles, so that you can see the Church and the Palace once you leave the opera. The part of the island's land where the Opera was built is called Dokøen, which means Dock Island. A few yards west of the work, you can still see an old dock and a pumping station. In addition to being accessible by car and bus, the Theater can also be reached by boat, and with the public transport system in Copenhagen you can get a boat ride for the Opera using a regular ticket.
