The Louise M. Davies Symphony Hall or commonly known as the Davies Symphony Hall is the premier concert hall component of the San Francisco War Memorial and Performing Arts Center, located at 201 Van Ness Avenue San Francisco, California. This 2,743-seater event center is home to the San Francisco Symphony. Built in 1980, the Symphony used to share its space with the San Francisco Opera and San Francisco Ballet in the War Memorial Opera House. However, upon the construction of the Davies Hall, the Symphony finally has its own event center for a year-round schedule. The venue was designed by Skidmore, Owings & Merrill and Pietro Belluschi along with the famous acoustical consultants Bolt, Beranek and Newman. Its sophisticated interior exudes a visually elegant impression. In 1984, the Fratelli Ruffatti electro-pneumatic pipe organ - one of its famous feats - was installed. In 1992, further developments of the hall were realized after its acoustical and mechanical facets were renovated under the direction of Kirkegaard Associates. Aside from the event hall, the venue also packs a music library, dressing rooms, and a private dining room for major guests.
