This mighty operation includes both the Palais Garnier, an attraction in itself, and the Opéra Bastille (2 place de la Bastille, 12th arrond.) a slate-colored behemoth that has loomed over the place de la Bastille since 1989. The company has since split its energies between the two venues. In theory, more operas are performed at the Bastille, which has more space and top-notch acoustics, and the Garnier, home of the Ballet de l’Opèra de Paris, focuses more on dance, but the reality is you can see either at both.
