Not all buildings in Paris are 100’s of years old. The Opéra Bastille was opened in 1989, the bicentennial of the French Revolution. It takes up almost an entire city block and one critic called it a ‘hippopotamus in a bathtub’ in that delightful French way of describing things. It was designed by Carlos Ott.
Getting tickets is very, very difficult. Performances are sold out months in advance.
