The Stopera is a building complex in Amsterdam, housing both the city hall of Amsterdam and the Muziektheater, the principal opera house in Amsterdam and the home of De Nederlandse Opera, Het Nationale Ballet, and the Holland Symfonia. The name "Stopera" is a portmanteau of stadhuis (Dutch: "city hall") and opera. The opera house building is shaped like a huge, massive block, with a curved front facing the city.
