The bank inside the tower

Albert Pissis's Anglo and London Paris National Bank of 1910 stands within the tower, its granite front carrying 38-foot Doric columns; its banking hall is the atrium the public open space occupies. The bronze Star Maiden in it is a 1985 cast of a figure Alexander Stirling Calder made for the 1915 Panama-Pacific International Exposition, commissioned with the permission of the sculptor's daughter Margaret Calder Hayes.

Sources disagree about the bank's date: Wikipedia gives 1910, SPUR's guide 1912.

Not yet documented: the developer, the early tenants and who designed the open space. The assessor records 1983 (on file, matching the POPOS requirement year), but Wikipedia records 1984 as the tower's completion year. Submit an update
