Forbes has named Fleur de Lys (above), the lavish Beverly Hills estate featured in this week's Classicist column, as the world's most expensive house currently on the market with its $125 million pricetag. The palatial mansion beat out Leona Helmsley's Dunnellen Hall in Greenwich, Conn., which had been listed at $125 million as well, but saw its price cut by $30 million back in October (Forbeshas not yet registered the change). Fleur de Lys has been on the market since 2007, but unlike some other major property owners, billionaire's ex Suzanne Saperstein has yet to slash the price. In compiling its list of the world's 10 most expensive estates, Forbes culled from property listings, high-end brokerages and conversations with real estate agents. "We include only publicly listed properties," they note.

"In Europe, especially, estates and luxury residences that might qualify are shopped privately for undisclosed prices."
