The St. Louis Cemetery in New Orleans, established in 1789, is one of the city’s most visited historic sites. Its above-ground tombs hold the remains of well-known figures, including Delphine LaLaurie and famed Voodoo practitioner Marie Laveau. Local lore says Laveau’s presence is still felt in the cemetery at night, and other legends speak of Civil War and yellow fever victims whose spirits linger among the rows of monuments.
