9. Aaron Spelling's Manor

Cindy Spelling, the widow of legendary TV producer Aaron Spelling, has listed the family's 56,000-square-foot (5,202-square-meter) mansion outside Los Angeles -- dubbed "The Manor" -- for $150 million. The home was built for Spelling in 1991, with all the bells and whistles the family demanded. The 123-room home, which covers 56,500 square feet (5,249 square meters) of living space, spans 6 acres (2.4 hectares) of prime Los Angeles real estate [source: USA Today].

In addition to the home's 123 rooms, you'll find an indoor skating rink, swimming pools, tennis court and bowling alley on the grounds. It also has some more unusual features, like a doll museum, a room used exclusively for wrapping presents and an entire floor dedicated to closet space [source: Daily Mail]. The grounds even include a private orchard, which might just keep the home's three kitchens fully stocked [source: Luxury Launches].
