				Vallejo's Petaluma Adobe
				
				Petaluma Adobe served as the center for General Mariano Guadalupe Vallejo's 66,000-acre working rancho from 1836-1846. It was once the largest privately owned adobe building in northern California; Vallejo sold the building and surrounding acres in 1857. The Native Sons of the Golden West acquired the adobe in 1910 and the State of California obtained it in 1951.
