Miller Outdoor Theatre brings free professional performances to an open-air stage in Hermann Park. The calendar moves through symphony, ballet, theater, jazz, film, dance, and cultural festivals, with covered seating below and a grassy hill made for blankets. Pack a picnic, arrive early for popular programs, and let the skyline and evening air join the show. At Miller Outdoor Theatre, give the strongest works a second look; the quieter details often carry the story.
