This controversial building -- it has been called a "beached whale" -- was designed by Canadian architect Carlos Ott, with curtains by Japanese designer Issey Miyake. Since the house's grand opening in July 1989, the Opéra National de Paris has presented works such as Mozart's Marriage of Figaro and Tchaikovsky's Queen of Spades. The main hall is the largest of any French opera house, with 2,700 seats, but the building also contains two smaller concert halls, including an intimate 250-seat room that usually hosts chamber music. Both traditional opera performances and symphony concerts are presented here, as well as classical and modern dance.
