War Memorial Opera House in San Francisco
Home to the San Francisco Opera and the San Francisco Ballet, the War Memorial Opera House, which opened in 1932, commemorates those who served in World War I. The landmark was designed by architect Arthur Brown, Jr., who also designed San Francisco City Hall. It's one of the last Beaux-Arts structures built in the United States, according to the opera house website.
The main hall seats 3,126 people under a blue vaulted ceiling from which an aluminum and glass-panel chandelier hangs. The opera house was heavily damaged in the 1989 Loma Prieta earthquake and was restored in 1992 with state-of-the-art equipment and re-upholstered plush velvet seats.
