In 1921, Hart purchased a ranch house and surrounding property. He built a 22 room mansion which today houses Hart's collection of western art, Native American artifacts, and early Hollywood memorabilia. Hart lived at the ranch nearly 20 years until his death in 1946. In his will, Hart gave the Horseshoe Ranch to the County of Los Angeles. It was to be set aside for the use and enjoyment of the public, at no charge.Today, the Horseshoe Ranch consists of 265 acres. Both the ranch house and the Hart residence are open to the public. An assortment of animals reside at Hart Park, including a small herd of bison which were a gift from the Walt Disney Studios in 1962.  (William S. Hart Ranch and Museum.
