Giannini's Bank of Italy.","why_significant":"It is the most significant surviving Giannini building because he launched the branch banking system here, which eventually made Bank of America the largest commercial bank in the world. The bank used it as headquarters from 1908 to 1921, and in 1909 Giannini and his directors decided here to open the San Jose branch, the first step toward the first statewide branch banking system in the United States.","narrative":"Opened on August 17, 1908, this eight-story bank building at Clay and Montgomery Streets in San Francisco served as headquarters of A.P. Giannini's Bank of Italy until 1921. F.T. Shea was the architect, though Giannini closely supervised design and construction. The steel-framed structure has a two-story base, a four-story shaft faced in granite and Bedford limestone, and a two-story crown with Ionic-style pilasters. Original interior features survive in the first-floor banking room, including marble counters, flooring and staircase, plaster ceilings in Renaissance colors, and a large vault. The building matters because Giannini launched his branch banking system from here. In 1909 he and his directors decided in a meeting room to open a San Jose branch, the first step toward the nation's first statewide branch system. The bank later became Bank of America, and the building remains a branch.","period_of_significance":"Site: 1908-21; Subject: 1904-49","architect_builder":"F. T.
