Grass Valley, which was originally known as Boston Ravine and later officially named Centerville, dates from the California Gold Rush, as does nearby Nevada City. When a post office was established in 1851, it was renamed Grass Valley the following year for unknown reasons. The town incorporated in 1860. Grass Valley is the location of the Empire Mine and North Star Mine, two of the richest mines in California. George Starr, manager of the Empire Mine, and William Bowers Bourn II, the mine owner, donated mine property which became Memorial Park.
