Built in 1928, this Tudor-style mansion was once the most expensive home in California. A gift from a father to a son, this estate proves that money doesn't buy happiness. The son, Ned Doheny, died in the house four months after moving in - an apparent murder-suicide. Now a public park with perfectly manicured lawns and the grounds are open to the public although the mansion is not. The interior of the mansion is only open to filming and special events and has made an appearance in dozens of movies and TV shows.
