Pío Pico State Historic Park is the site of El Ranchito, also known as the Pío Pico Adobe or Pío Pico Mansion, the final home of Pío Pico, the last Governor of Alta California under Mexican rule and a pivotal figure in early California history. Located in Whittier, California, at 6003 Pioneer Blvd. near Whittier Blvd. and Interstate 605, it is California Historical Landmark No. 127, listed as "Casa de Governor Pío Pico". Just west of the park is the San Gabriel River. Across the river is the city that bears his name—Pico Rivera. The park consists of the adobe and about three acres of surrounding land.
Starting in 1848, after the Mexican–American War, Pío Pico began acquiring the 10,000-acre Rancho Paso de Bartolo, and built a home in 1853. The home was damaged by the flooding of 1867, which set the San Gabriel River to its present course, and was nearly destroyed in 1882 by flooding.
