Opéra de la Bastille, the ultramodern facility built in 1989 and designed by architect Carlos Ott, has taken over the role of Paris's main opera house from the Opéra Garnier. Like the building, performances tend to be on the avant-garde side -- you're just as likely to see a contemporary adaptation of La Bohème as you are to hear Kafka set to music. Tickets for the Opéra de Paris productions range from EUR10 to EUR114 and go on sale at the box office two weeks before any given show or a month ahead by phone. The opera season usually runs September through July, and the box office is open Monday-Saturday 11-6:30. The Web site is very informative and complete and also allows you to order tickets.
