San Francisco - Portsmouth Square - 1860
(view facing west)

 

Yerba Buena was founded in 1835 when Captain William A. Richardson was made Harbor Master by Governor Figueroa, and set up his tent at what is now Grant Ave., between Clay and Washington streets (near Yerba Buena Cove), the soon-to-be Portsmouth Square.

In 1846, the United States took Yerba Buena from Mexico, and later that year, on July 8, Commodore J.B. Montgomery sailed into San Francisco Bay on board the USS Portsmouth. On July 9 Commodore Montgomery raised the United States flag in the plaza in front of the Mexican Custom House, hence the name Portsmouth Plaza or Square. In 1847, Yerba Buena is renamed San Francisco by the United States. Portsmouth Square has remained an open space in San Franciso to the present.
