The Tobin Center for the Performing Arts is San Antonio's performing arts center. Located next to the San Antonio Riverwalk, it is named for Robert L. B. Tobin, one of the city's most prominent residents.
The 1738-seat venue was first built in 1926 as the San Antonio Municipal Auditorium by Atlee Ayres. In 2014, it was renovated and expanded by the Seattle-based LMN Architects and the local firm Marmon Mok Architecture.
