Montgomery Block

The Montgomery Block was a four-story brick building at 600 Montgomery Street that featured innovative earthquake-resistant foundations when it was completed. Its base of crossed redwood logs and straw provided unusual stability against ground movement and made it structurally advanced for its time.

The structure was built in 1853 as San Francisco's first fireproof building and survived the 1906 earthquake without collapsing. Its demolition came in 1959 to make way for construction of the Transamerica Pyramid.

The place served as a gathering point for artists, writers, and bohemians who occupied studios, galleries, and gathering spaces within its walls. This creative community shaped the character of the location and made it known throughout the city as a cultural hub.

The exact location of the former building is marked by a commemorative plaque in the north lobby of the current Transamerica Building. Visitors can find this marker easily when entering the tower.

The structure earned the nickname Monkey Block, a playful name that reflected the rough and rowdy character of the sailors and dockworkers who frequented the place. This casual, unpolished atmosphere set it apart from other buildings in the city at the time.
