Sonoma State Historic Park is a California State Park located in the center of Sonoma, California. The park consists of six sites: the Mission San Francisco Solano, the Sonoma Barracks (sometimes called the Presidio of Sonoma), the Blue Wing Inn, La Casa Grande, Lachryma Montis, and the Toscano Hotel. The park was founded in 1909 and originally contained only the Mission San Francisco Solano. The State of California has, over the years, added additional historic locations to the Park.
