San Antonio Municipal Auditorium, former multi-purpose hall in San Antonio, Texas, United States

The San Antonio Municipal Auditorium was a 12-sided limestone arena at 100 Auditorium Circle, designed in Spanish Colonial Revival style by Atlee Ayres, Robert M. Ayres, George Willis and Emmett Jackson. Its carved stone and arcade entrance were flanked by a domed tower on each side, under a roof of red stone tile and metal. The interior had two-level horseshoe-shaped seating for 1,738 patrons. Most of it was razed in 2009; portions of the exterior were preserved and incorporated into the Tobin Center for the Performing Arts, which opened in 2014.

The limestone arena was built in 1926 as a memorial to American soldiers killed in World War I, designed in Spanish Colonial Revival style by Atlee Ayres, his son Robert M. Ayres, George Willis and Emmett Jackson. The American Institute of Architects gave the architects a gold medal in 1929, and the building joined the National Register of Historic Places in 1981. A 1979 fire destroyed much of the interior; a 1981 bond referendum funded restoration, and the auditorium was rededicated in 1985. Most of it was razed in 2009 for the Tobin Center for the Performing Arts, which opened in 2014 with portions of the old exterior preserved.

The auditorium's name and purpose tie it to World War I: it was built as a memorial to American soldiers killed in that war and forms part of Veterans Memorial Plaza. Nearby stand the 1938 white marble War Mothers Memorial, Austin Deuel's 1986 Hill 881 South for Vietnam veterans, and Jonas Perkins's 1994 Night Watch for the Korean War.

The auditorium stood at 100 Auditorium Circle on Veterans Memorial Plaza, a 6-acre site partly bought from the Ursuline Academy. Most of it was razed in 2009; the preserved exterior portions now form part of the Tobin Center for the Performing Arts, which opened in 2014. Look for the War Mothers Memorial at the corner and the Korean War Memorial across from the former front entrance.

The 36 by 75 ft stage curtain, weighing 5,600 lb, carried Hugo D. Pohl's painting Founding of San Antonio, showing the 1718 founding of Presidio San Antonio de Bexar alongside Alamo defenders James Bowie, Davy Crockett, William B. Travis and James Butler Bonham. A 1979 fire left it beyond repair.
