The LaLaurie Mansion is widely considered the most haunted building in New Orleans. Located at 1140 Royal Street in the French Quarter, the home was originally occupied by physician Louis LaLaurie and his wife Delphine.
In 1832 rumors of Madame LaLaurie's cruel treatment of enslaved workers began to circulate. Stories that she had chained a cook to the fireplace, chased a young woman off the roof, and performed perverse experiments on living persons were featured in tabloids like the New Orleans Bee.
When a terrible fire broke out at the mansion in April of 1834, seven mutilated enslaved persons were reportedly found shackled in the attic. Their bodies revealed years of torture ranging from skull fractures and whipping scars, to missing fingernails and gouged eyes. The discovery enraged local citizens who chased Madame LaLaurie from the residence and from New Orleans.
Although Delphine never returned to the mansion, the spirits of her enslaved workers have reportedly remained. Many former residents and visitors claim to experience screams of agony coming from the attic, as well as apparitions of enslaved people in the building's courtyard. Recent owner Nicolas Cage confirmed these tales and concluded that "other people have beachfront property; I have ghost front property".
