The building on the banks of the Amstel River in Amsterdam is home to The Dutch Opera, The National Ballet, and the Holland Symphonia.  It is one element of a complex known as "Stopera", a portmanteau word combining stadhuis (city hall) and opera.  After decades of argument and abortive attempts to give the city a new city hall and an opera house, it was finally decided to put them adjacent to each other.

Its Wikipedia page describes the opera house as being, "... shaped like a huge, massive block, with a curved front facing the city. Its facade is covered in a red-orange brick and corrugated metal panels. The curved face of the theatre is faced with white marble punctuated by large windows that provide panoramic views of the river from the curved interior foyers and multi-level terraces."

It would be wrong to conclude that everyone in Amsterdam was happy that a decision was finally made about this project.  As the Opera House website tells you, "... Riots broke out as the first piles were driven into the ground. The protest was given the name: 'Van Stopera naar Slopera' (roughly meaning 'From building to demolition'). Construction work was postponed for a month before a definitive start could be made. The Amsterdam Music Theatre was officially opened on 23 September 1986 and the Amsterdam city council moved into its new city hall in September 1988. The famous Waterlooplein flea market, which had been temporarily moved to the Rapenburgerstraat, returned to the square next to the new city hall in the same year."
