For $15 million, would you want to own this haunted mansion?

One of America’s most haunted houses – with a secret bar concealed behind a bathroom mirror, to boot – has been offered to a brave new owner for more than $15 million.

New Orleans’ LaLaurie Mansion, built in 1832, was once owned by Hollywood movie star Nicholas Cage, but he wasn’t the only one walking the vast halls.

Tall tales abound that the classical estate is the most haunted house in the historic US city. The original owners were a cruel socialite couple, Dr. Louis LaLaurie and his wife Delphine LaLaurie. This marriage was Delphine’s third – her previous husbands died mysteriously.

The couple kept slaves, and a fire ripped through the mansion in 1983, allegedly started by one hoping for rescue. Firefighters who entered discovered the horrors of how the slaves were treated, and the LaLaurie family fled to Paris after locals threatened to storm the property.

Even with its dark past, the mansion has price hopes of $US10.25 million ($AU15,185,000), through US-based listing portals, and is one of the homes featured in chilling ghost tours of the city.

The listing touches on the legend.

“Steeped in local lore, the LaLaurie Mansion stands as a pinnacle of historical significance and architectural grandeur in the heart of New Orleans’ Vieux Carre,” the Realtor listing says. “This Empire-style antebellum masterpiece seamlessly blends period details with modern comforts and was curated to elevate every corner of its expanse.”

A rooftop deck and deep balcony is positioned to capture the hubbub of the famous French Quarter below.

But that is not the most astonishing floorplan feature. A speakeasy-style bar and lounge can be found behind a mirror in the main en suite.

“The third floor hosts three luxurious bedroom suites, including a striking red lacquered primary suite featuring a speakeasy accessible through a hidden bathroom door,” the listing reveals.

“Whether for historical intrigue or contemporary luxury, the LaLaurie Mansion invites discerning buyers to experience a unique blend of past and present in the heart of New Orleans.”

Cage bought the property in 2007 but his ownership was short lived. His bank foreclosed on the loan, and the current vendor purchased it and embarked on renovations.
