A San Francisco mansion where the late actor Robin Williams raised his children for more than two decades has sold for $18 million.

The Italian Renaissance-style villa, built in 1926, is located in the exclusive Sea Cliff neighborhood and spans nearly 11,000 square feet across three stories, Kron4 reported.

The property, at 540 El Camino Del Mar, offers panoramic views of the Golden Gate Bridge, Marin Headlands and the Pacific Ocean.

Designed by architect Earle Bertz, the property combines old-world elegance with grandeur, featuring six bedrooms, six bathrooms and manicured gardens behind a gated perimeter.

Williams, who won an Oscar for “Good Will Hunting” and starred in beloved films like “Mrs. Doubtfire,” purchased the home with his then-wife, producer Marsha Garces Williams, in 1991 for $3.2 million.

The couple raised their children in the home before Garces Williams retained ownership following their 2010 divorce.

Initially listed for $25 million in 2023, the mansion was described as “one of San Francisco’s most remarkable estate properties,” combining “period elegance and luxurious scale with modern sensibilities, joy and playfulness,” according to the previous listing.

The property, adorned with secret rooms and hidden passageways, was designed for his children.

“It’s a beautiful, happy house,” Marsha previously told Mansion Global when it first listed, adding that now that their children have grown, she was ready to downsize.

“We had many, many fantastic years of fun and play and joy there.”

Additional perks include a library and a media room, both boasting French doors that lead to the outdoors.

“Marsha and Robin Williams took the house down to the studs and rebuilt it in the early ’90s, updating all the major systems,” Compass agent Steven Mavromihalis previously told The Post in a statement.

“They expanded the home to its current 10,598 square feet on three levels. However they took great pains to preserve the rare and valuable building materials used in 1926, which are simply no longer available in the construction of modern homes.”

Williams died by suicide in 2014 at the age of 63. Only several years after his death, it was revealed that he had suffered from Lewy body dementia.
