Here is the link to the site.  
I am sure someone else will be able to explain better than I the history of the Castle.
And, I am hoping that someone can tell me the name of the Ranch that was turned into a military base...years ago it said you could stay there.  I would like to know if you can still stay there.  
Darn it but I lost the site..........
Oh, um, yes, the story is really magnificent about Randolph Hearst.  A publishing magnet? {is that the word?}  The castle, wow, you really need to google it or something, it is too much to just put in a post.  He built the castle and brought all of the finest things, made it a playground for he and his friends.
