A Brooklyn Heights mansion known as the fictional home of mob boss Don Corrado in “Prizzi’s Honor” is on the market for an over-the-top $40 million.

That’s a record asking price in Brooklyn — and blows away price tags on many of Manhattan’s fanciest Fifth Avenue town houses.

The 15-bedroom, 16-bath residence is owned by Jeff Keil, a retired banker and former president of Republic New York Corp., who bought the majestic home for $2.3 million in 1991.

The 18,000-square-foot mansion at 3 Pierrepont Place, listed by Corcoran broker Vicki Negron, overlooks the Brooklyn Heights Promenade and comes with great views of New York Harbor. It also boasts fabulous historic details, including original fireplaces, high ceilings and a dramatic central staircase with a skylight, and 9,000 square feet of outdoor garden space.

It was built in 1856 for Abiel Abbott Low, a businessman who got rich trading tea and silks with China.

Low’s son Seth was president of Columbia College and mayor of Brooklyn before becoming mayor of New York City in 1902.

The mansion’s architect, Richard Upjohn, also designed the current Trinity Church Wall Street and St. Thomas Episcopal Church on Fifth Avenue.

The mansion is currently divided into eight occupied apartments, but can be delivered vacant, according to the brokerage firm.
