Film Festival on Rathausplatz in Vienna
The Film Festival on Rathausplatz turns Vienna's City Hall square into a free open-air cinema for roughly two months each summer, screening recorded opera, concerts, ballet and musicals on a giant screen alongside international food stalls. No ticket is required for either the food court or the nightly screenings.
The Rathausplatz film festival opened in 1991 with a single premise -- recorded opera performances projected free on a giant screen in front of Vienna's City Hall -- and has since stretched that idea across an entire summer rather than a single week.
