city, Marin county, western California, U.S. It lies along San Francisco Bay just north of San Francisco across the Golden Gate Bridge. It was founded in 1838 by William Richardson, who had received a Mexican land grant called Rancho Sausalito, named by Spanish explorers for its little willow trees. Taking advantage of the village's fine natural cove, Richardson sold fresh water and vegetables, raised cattle, and collected port fees. After the Gold Rush of 1849, Richardson sold the land to Charles Botts, who had planned a city and a naval shipyard. However, the city failed when a naval shipyard was established at Mare Island off Vallejo. With the arrival of the North Pacific Coast Railroad in 1871, Sausalito grew as a seaport and transportation junction. After the completion of the Golden Gate Bridge in 1937, it developed as a bedroom community of San Francisco, with tourism and services as its economic mainstays. The city attracted many artists and is home to several art galleries and festivals. It is also a popular shopping and recreational area, with a boardwalk along the bay and scenic views. The Bay Area Discovery Museum is an interactive children's museum. Angel Island State Park is located offshore east of the city, and Golden Gate National Recreation Area is to the west. Inc. 1893.
