At nearly 11,000 seats, The Muny is America's oldest and largest outdoor musical theatre. Founded in 1919, our mission is to enrich lives by producing exceptional musical theatre, accessible to all. Generations have enjoyed everything from operettas and ballets to concerts and musicals. Hundreds of thousands join us every summer for the best of Broadway. And each night, nearly 1,500 guests attend The Muny--absolutely free of charge--continuing a remarkable St. Louis tradition under the stars in Forest Park
