Hearst Castle is a National and California Historical Landmark mansion, It was the creation of two extraordinary individuals, William Randolph Hearst and architect Julia Morgan. Their collaboration, which began in 1919 and continued for nearly 30 years, transformed an informal hilltop campsite into the world-famous Hearst Castle -- a magnificent 115-room main house plus guesthouses, pools, and 8 acres of cultivated gardens. The main house itself, "La Casa Grande," is a grand setting for Hearst's collection of European antiques and art pieces. It was also a most fitting site for hosting the many influential guests who stayed at Hearst's San Simeon ranch. Guests included President Calvin Coolidge, Winston Churchill, George Bernard Shaw, Charles Lindbergh, Charlie Chaplin, and a diverse array of luminaries from show business and publishing industries.
