Hearst Castle, known formally as La Cuesta Encantada (Spanish for 'The Enchanted Hill'), is a historic estate in San Simeon, located on the Central Coast of California. Conceived by William Randolph Hearst, the publishing tycoon, and his architect Julia Morgan, the castle was built between 1919 and 1947. Today, Hearst Castle is a museum open to the public as a California State Park and registered as a National Historic Landmark and California Historical Landmark. George Hearst, William Randolph Hearst's father, had purchased the original 40,000-acre (63 sq mi) estate in 1865 and Camp Hill, the site for the future Hearst Castle, was used for family camping vacations during Hearst's youth. Soon after the death of his mother, Phoebe Hearst, in 1919, William Randolph commissioned the architectural pioneer Julia Morgan to build "something a little more comfortable up on the hill", the genesis of the present castle.
