It’s a rock star’s museum.

An Upper West Side penthouse duplex once owned by Sting will list for $45 million, Gimme Shelter can reveal. The stellar skypad has been empty, devoid of occupancy, ever since he moved out.

“No one has lived there since Sting,” listing broker Michael Lorber, of Douglas Elliman, told Gimme Shelter. 

That $45 million ask is $5 million less than what the sellers paid when they bought it from Sting and Trudie Styler back in 2018.

The spread is on the 16th and 17th floors of 15 Central Park West, the iconic Robert A.M. Stern-designed residential building. 

While the two-towered limestone structure was positively swoonworthy when it first launched in 2007, it has since been overshadowed by its taller relative, 220 Central Park South, which was also designed by Stern, and other new-construction luxury condos.

Nevertheless 15 CPW is still known as one of the city’s best trophy buildings. Past and present residents have included Robert De Niro, Denzel Washington, Mark Wahlberg, Kelsey Grammer, Alex Rodriguez and NASCAR champ Jeff Gordon.

Sting, using his full name, Gordon Summer, bought the residence for $27 million from the sponsor in 2007.

Sting and Styler then hired Lee Mindel to design the interiors. That means whoever buys the penthouse gets it with Sting and Styler’s personal custom touches — including a round gas fireplace in the great room that remains intact. Sting first listed the penthouse for $56 million in 2017, before selling it a year later for $50 million. The owners appear to be Asian investors, sources say.

The lofty residence also comes with permit plans to redesign the space from British architect Lord Norman Foster, 90, of Foster + Partners.

“The plans are in place but they were never done,” Lorber said. 

The three- to four-bedroom penthouse is in the House section of the tower, and it comes with more than 44 feet of frontage overlooking Central Park.

The aerie features dazzling views from two floors and a 400-square-foot terrace. Currently set up as a three-bedroom, it also comes with a large home office that could also function as a fourth bedroom. 

The home also boasts a library with built-in bookshelf walls. There’s also an open dining room/media room and a streamlined chef’s kitchen with its own spiral staircase that leads to the second level — also accessed by a separate entrance off the elevator.

On the upper floor, a main bedroom suite overlooks Central Park and features two large dressing rooms, two spa-like baths — one with serene park and city views — and a sauna.   

The 43-story building features just over 200 units.

Amenities include a motor court, a skylit lap pool, a business center and a private restaurant.
