The Pacific-Union Club – California Street, San Francisco, California

The Pacific-Union Club is a private social club located at 1000 California Street in San Francisco, California, at the top of Nob Hill. It was founded in 1889 as a merger of two earlier clubs: the Pacific Club (founded 1852) and the Union Club (founded 1854).

The clubhouse was built as the home for the silver magnate James Clair Flood. The former Flood Mansion is located in the Nob Hill neighborhood. It was designed by Willis Polk. It is considered the first brownstone constructed west of the Mississippi River. Along with the Fairmont Hotel across the street, it was the only structure in the area to survive the San Francisco earthquake and fire of 1906.

This club figured prominently in the history of the west coast of the United States. Many prominent citizens have been active among its membership. To this day, the club’s membership remains all male per its charter.
