William S. Hart, also known as "Two Gun Bill," was the first cowboy movie star during the silent film era. He made almost 70 silent movies from 1914 to 1925, and donated his sprawling 265-acre ranch for the public to enjoy. The park features Hart’s home which is now a museum filled with his personal effects and movie paraphernalia, along with Native American artifacts and Western art.
The William S. Hart Museum, a satellite of the Natural History Museum of Los Angeles County, offers free guided tours year round and special events such as Music in the Mansion concerts, and A Day at the Ranch.
