Pio Pico State Historic Park

Pio Pico State Historic Park preserves a 19th-century adobe house set along the San Gabriel River that shows how early California residents built their homes. The site includes the main dwelling with surrounding grounds and outbuildings that give a sense of ranch life from that period.

The house was built in 1853 by Pio Pico, the last governor of Mexican California, who made it his final home. It became a state park in 1927 when community members worked to save and protect this piece of California's past.

The building displays Mexican adobe construction techniques blended with later American elements that arrived after statehood. Walking through its rooms, you see how two building traditions meet in the walls and layout.

The park is open daily and you can walk the grounds at your own pace or join a guided tour to learn more about the site. There are signs and information displays throughout, and the pathways are easy to follow for most visitors.

The property once sprawled across thousands of acres as a working ranch before shrinking to a small historic site in the 20th century. This transformation mirrors how California shifted from frontier ranches to preserving pieces of its past for public visits.
