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 Opera National de Paris has presented works like 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 music critics have lambasted the acoustics. The building contains two other 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 both classical and modern dance. Several concerts are given for free in honor of certain French holidays.
