This is the Hearst Castle, located in San Simeon, California...It was built by billionare William Randolph Hearst in the first part of the 1900`s...It is now a museum, open to the public and a big tourist attraction in California...I have not seen it myself yet, but I think there is an admission fee...If I can find a travel partner on the internet, maybe it would be fun to visit this place and also other interesting places...I don`t enjoy going to places alone, however, it`s too depressing that way...It`s a lot more enjoyable when you can share your experiences with a friend...But, anyway, the movie "Citizen Kane" (1941) with Orson Welles is based on the life of William Randolph Hearst, the newspaper tycoon....
