The seller is real estate entrepreneur Jeff Greene, who owns properties in Florida, New York and California.

The Mediterranean-style villa, called Palazzo di Amore, sits on a knoll behind three sets of gates. Reached by a quarter-mile-long tree-lined drive, the mansion is approached through a vineyard and has canyon and cityscape views. Inside, the two-story marble entry features two sweeping staircases.

Greene spent eight years expanding the villa, which he calls "a palace for the modern era." He finished the second floor of the main residence and built a 15,000-square-foot entertainment complex containing a disco/ballroom with a revolving dance floor, a DJ booth and a laser-light system. Up to 250 guests can be seated there for dining.

A floating-style glass-floor walkway over pools lined by 70-year-old olive trees leads to the complex, which has limestone floors with marble and maple inlay and hand-painted ceilings. Other features of the entertainment center are a 50-seat theater, a bowling alley and a game room.
