Rancho Tesoro Historic Park
(Valencia, CA)

Located in Valencia, California, the Tesoro Adobe was built in the 1920’s and 1930’s by noted western film actor Harry Carey. Credited with at least 233 movies, Carey’s prolific film career included “Shooting Straight” (1918), “Mr. Smith Goes to Washington” (1939), and “Red River” (1948). The Tesoro Adobe hosted the western elite of the day, including John Wayne, William S. Hart, and Gary Cooper.

The developer of the Tesoro residential community that surrounds the park, Montalvo Properties LLC, donated the Adobe to the County in June 2005. The 1,000-acre ranch is now a Los Angeles County park.
