100 Montgomery Street, Office skyscraper in Financial District, San Francisco, United States.

100 Montgomery Street is an office tower in the Financial District with 25 floors and a distinctive white marble exterior. The building showcases aluminum-framed windows in art-deco style that run along its entire facade.

The tower was completed in 1955 as part of the post-World War II expansion of San Francisco's business district. It emerged during a period of strong economic growth in the city.

The building's name comes from the Equitable Life Insurance Company, which used it as its headquarters. Today its tenant roster mixes finance and technology: Wells Fargo Bank and City National Bank share the address with Snapfish, Veeva Systems and Blend Labs. Visitors can read the contrast in the facade itself, where white marble panels sit against aluminum art-deco window framing.

The building sits in the heart of the Financial District with easy access to public transportation. Its location provides good connectivity to major business hubs and transport connections throughout the neighborhood.

The white marble facade contrasts with aluminum Art Deco window framing, a combination architect William Peugh used on one of San Francisco's first post-World War II office towers. Completed in 1955 at 354 feet, it served as headquarters of the Equitable Life Insurance Company.
