Site of First California State Fair

California's first state fair was held on this site on October 4, 1854. Sponsored by the California State Agricultural Society, the exhibition of "horses, cattle, mules, and other stock, and agricultural, mechanical, and domestic manufacture and productions" promoted the new state's growing agricultural industry. A different city held the fair each year, until Sacramento became the permanent location in 1861.
