In the film "Citizen Kane", what is the name of the palatial estate owned by Charles Foster Kane?

Xanadu is the name of the palatial estate owned by Charles Foster Kane in the 1941 film "Citizen Kane". This mansion (Xanadu) is part of a vast fictional estate that is located in the U.S. state of Florida. The estate derives its name from the ancient city of Xanadu, known for its splendor. The real Hearst Castle in San Simeon, California, was the obvious inspiration for Xanadu, due to the Hearst/Kane comparison which was a central concern of the film.

Xanadu was built on an immense "private mountain" located on the "deserts of the Gulf Coast" in Florida. It was described as being the world's largest private estate. "Cost: no man can say," according to the newsreel at the beginning of the film. The newsreel directly quotes from Samuel Taylor Coleridge's poem 'Kubla Khan', which tells of the title character's erection of a 'stately pleasure-dome' in the city of Xanadu. The newsreel next states that Kane specifically conceived his estate for Susan Alexander, his second wife. However, Susan grew to hate Xanadu, calling it "forty-nine thousand acres (76 square miles) of nothing but scenery and statues."

"Citizen Kane" is an epic film that was directed by Orson Welles. A film where Welles was also its producer and co-screenwriter, besides being one of the stars with Joseph Cotten, Dorothy Comingore, Everett Sloane, Ray Collins, George Coulouris, and Agnes Moorehead. The film won an Academy Award for Best Writing (Original Screenplay); it had been nominated in 9 categories.
