Arguably the most expensive home in the United States, the Fleur de Lys in the exclusive Holmby Hills enclave of Los Angeles has been on the market since 2007. The price tag? An unapologetic $125 million.
The 15-bedroom, 45,000-square-foot (3,809-square-meter) mansion -- which was inspired by the 17th-century French chateau Vaux-le-Vicomte (itself an inspiration for Louis XIV's Versailles) -- was built by Texas billionaires David and Suzanne Saperstein, but ended up in Suzanne's hands after a nasty divorce involving his affair with a Swedish nanny [source: W Magazine].
Among its authentic Francophile flourishes, the home's exterior walls are covered with imported, handpicked French limestone. The interior is bedecked with 24-karat gold trim and museum-quality furniture, including Napoleon's favorite chair and Marie Antoinette's personal fire screen [source: HGTV]. If you get bored ogling the interior, you can always watch a Jean-Luc Godard flick in the 50-seat screening room [source: Forbes].
The next home isn't just opulent -- it's got a pretty spooky history.
