In the $120 million stone-and-glass Cité de la Musique, this museum serves as a tribute and testament to music. You can view 4,500 instruments from the 16th century to the present as well as paintings, engravings, and sculptures that relate to musical history. It's all here: cornets disguised as snakes, mandolins, lutes, zithers, music boxes, even a postwar electric guitar. Models of the world's great concert halls and interactive display areas give you a chance to hear and better understand musical art and technology.
