Cast in 1679 in Lima, Peru, the 8-pound San Francisco bears the coat of arms of Don Baltasar de la Cueva Henriquez y Saaverdra, 24th Viceroy of Peru.


Originally emplaced at the Castillo de San Joaquin to guard the San Francisco Bay, the cannon was subsequently moved to Sonoma at the request of the Mexican Governor of Alta California. On July 20, 1846, Captain Montgomery of the U.S.S. Portsmouth sent a military detachment to retrieve the cannon and return it to the Presidio.

The San Francisco Air value Resource group is developing a car free tourism website for visitors to San Francisco. Many visitors to San Francisco select to drive while plentiful public transportation options exist - options that could save visitors both time and cash. The team's car free plan aims to take present information on transportation options in the City and make the information more accessible and available.


The team has also facilitated cartography updates on the Transit to Trail chart, published as a supplement in the April-June 2009 Bay Nature Magazine. This map provides information about using transit to reach San Francisco area parks and recreation and will be available on the car free website soon. If you would like information on the San Francisco Resource Team on Air Quality please contact Stephanie Anderson at 510-763-2500 ext.1.
