Located on nearly eight acres in the heart of Hermann Park, Miller Outdoor Theatre is the only free open-air theatre of its kind in the United States. It is a home away from home for some of Houston's most dynamic arts organizations such as HITS Unicorn Theater, Houston Grand Opera, the Houston Ebony Opera Guild, Festival Chicano, Houston Symphony, and a host of other multi-cultural groups and theater companies. Every performance in our March to November season is free.
