2. The Hearst Mansion (Beverly Hills)
This 50,000 square foot Beverly Hills manse — and honeymoon spot of JFK and Jackie — melds grand Italian and Spanish architecture, including a 50-foot entrance hall. Once worth $165 million, the legendary estate was put on the market in 2012 by bankrupt owner Leonard Ross for $95 million and hauls in $600,000 a month in rental rates.
