456 Montgomery Plaza, Commercial skyscraper in Financial District, San Francisco, United States

456 Montgomery Plaza is a 26-story, 379 ft (116 m) steel-frame office tower completed in August 1985. It rises above two circa-1907 granite banking facades: the former Borel & Co. bank by Albert Pissis at the main entrance, and the former Italian American Bank by Howard & Galloway at Montgomery and Sacramento Streets. A sunken privately owned public space lies on the site.

456 Montgomery Plaza was completed in August 1985 as a 26-story steel-frame tower. Its base keeps two circa 1907 granite banking facades: the former Borel & Co. bank by Albert Pissis, now the main entrance at 456 Montgomery, and the former Italian American Bank headquarters by Howard & Galloway at Montgomery and Sacramento Streets, fronting leased banking space at 460 Montgomery.

The base keeps two 1907 granite temple facades. The main entrance at 456 Montgomery is the former Borel & Co. bank by Albert Pissis; the corner facade at Montgomery and Sacramento is the former Italian American Bank by Howard & Galloway, now fronting leased banking space at 460 Montgomery.

The sunken privately owned public space sits within the block bounded by Montgomery and Sacramento Streets, entered from the sidewalks around the tower's base. Look for the two granite temple facades: the Borel & Co. bank entrance at 456 Montgomery and the former Italian American Bank at the Montgomery–Sacramento corner, now fronting a leased banking space at 460 Montgomery.

The tower rises above two circa-1907 granite banking facades kept in place: the former Borel & Co. bank by Albert Pissis at 456 Montgomery, and the former Italian American Bank by Howard & Galloway at Montgomery and Sacramento. The same facade-retention approach appears at 353 Sacramento and One Sansome.
