The famous Amsterdam Philharmonics is called Concertgebouw (translation: Concert Building). It closes the Museumplein from the south-west, facing the Rijksmuseum. The classicist 19 c. building has today a modern annex, with more space for the booking office, cashiers and the reception of the audience. Concertgebouw serves as home to the famous The Royal Concertgebouw Orchestra, as well as The Dutch Philharmonic Orchestra and The Dutch Chamber Orchestra.Concertgebouw big concert hall – Grote Zaal, is internationally recognized for its exceptional acoustics. The whole building has been completed in 1886, but it had been opened only two years later, when its orchestra conducted by Henri Viotta gave its first concert, on Wednesday 11 April 1888. Since then, the building and the Concertgebouw Orchestra have an uninterrupted reputation among music lovers as of one of the best in the world. The Concertgebouw building received an additional, modern wing and has been thoroughly restored in the years 1982-1995, without an interruption of its concert activity.
