Louise M. Davies Symphony Hall is the concert hall component of the San Francisco War Memorial and Performing Arts Center in San Francisco, California. The 2,743-seat hall was completed in 1980 at a cost of US$28 million to give the San Francisco Symphony a permanent home. Previously, the symphony shared the neighboring War Memorial Opera House with the San Francisco Opera and San Francisco Ballet. The construction of Davies Hall allowed the symphony to expand to a full-time, year-round schedule.
