The Bank of California Building is a 1908 Greco-Roman style structure with a brutalist, 312feet, 22-story tower annexed in 1967 at 400 California Street in the financial district of San Francisco, California.[2]
Union Bank acquired the building in 1996 as part of its merger with Bank of California.[3] It was one of the first commercial buildings to be completed following the 1906 San Francisco earthquake, leading to a rebirth of the city's financial district.[4] Construction was based on the Knickerbocker Trust Company building in New York City.[5]
