Like a nuclear bunker for the Hollywood set, this 50,000-square-foot mansion hides most of its glamour underground.
The subterranean luxury begins with a 10,000-square-foot, Moroccan-style spa that offers more opulence than many five-star hotels: a sauna, meditation rooms, baths and an indoor pool surrounded by archways that were constructed by 300 nomadic Moroccan tribesmen and assembled at the home's location just outside Los Angeles.
"It's literally the most extraordinary work of art I've ever seen," said listing agent Marcie Hartley of Hilton & Hyland.
An actual artist lived in the home for 10 years doing gold-leaf work, from religious figures in the chapel to faux shelves in the library that conceal a powder room.
Beneath ground with the grand spa is a five-story tennis court where Pete Sampras played.
It transforms into a banquet hall that seats 350 people, has an adjacent catering kitchen and opens to an outdoor clay tennis court, an outdoor pool and a large lawn with a pizza oven.
The yard also features a bocce court flanked by citrus trees, 70-year-old carob trees along the driveway and herb gardens overlooking the city.
The owner, shrimp importing CEO John Blazevich, took 17 years to build the mansion, finishing in 2002.
The mansion delves downward because of a community rule that homes have only a single story above ground, according to the Los Angeles Times. All 9 bedrooms and many of the 25 bathrooms are on the 20,000-square-foot, above-ground level.
