Bank of California Building (San Francisco)

The Bank of California Building is a 1908 Greco-Roman style structure with a brutalist, 312 ft, 22-story tower annexed in 1967 at 400 California Street in the financial district of San Francisco, California.

Union Bank acquired the building in 1996 as part of its merger with Bank of California. 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. Construction was based on the Knickerbocker Trust Company building in New York City.
