One of them has a 24 karat-gold-lined swimming pool. Another is on 90 acres of untouched California land. One was designed by an award-winning architect; another employed master craftsmen to install custom features. Click ahead to see them all.

The hefty price tag on this estate, which has never before hit the market, may be less attributable to the circa-1941 house itself and more owing to the three parcels of land making up 91 acres of beautiful property. Old growth oaks, open meadows, and bordered by Huddart Park, the painting-like grounds also include a gate house, a caretaker's cottage and a school.

Following a $25 million price drop, this Ocean Drive mansion is practically a bargain. Well—except that it still costs $100 million. Built in 1930, this house is replete with hand-painted frescoes and an observatory. It would be difficult to find a more over-the-top feature, though than the courtyard's 54-foot mosaic-tiled 24-karat gold lined pool.

Coming in at the No. 1 is the mansion called Fleur de Lys in the Holmbly Hills section of Bel-Air. The enormous mansion built by David Saperstein, and now belonging to his ex-wife, Suzanne, has been on and off the market since 2007. The pair divorced soon after the mansion was completed, so this estate has hardly even been lived in. Listed among the estate's possible interested buyers was Petra Ecclestone, but it was off the market until the day she bought the Spelling Manor in the same neighborhood, after which Fleur de Lys relisted. The house takes normal mansion amenities and supersizes them, so the garage houses nine cars and the screening room seats 50.
