San Francisco War Memorial – San Francisco, California

The cornerstones of the War Memorial Opera House and Veterans Building were laid on November 11, 1931 and has been home to the San Francisco Opera since it opened on October 15, 1932. In June of 1945, the two original buildings of the San Francisco War Memorial served as the birthplace of the United Nations. Most of the plenary sessions of the Conference took place in the War Memorial Opera House, but it was on the stage of the Veterans Auditorium (now the Herbst Theatre) that President Truman and other heads of state and dignitaries signed the United Nations Charter on June 26, 1945.

Today, the stately building is host to a variety of events. In addition to opera and ballet performances, the 3,146 seat auditorium is available for special presentations, lectures and concerts. The War Memorial Opera House is one of the Bay Area’s most sought-after and unique venues, offering modern technology and the ambience of Old World theater.

SOPREMA’s advanced PMMA membrane system, ALSAN® RS 230 was chosen for waterproofing this international landmark because of the ease of installation in tight areas and short time schedule.
