Saint Louis Cemetery is the name of three Roman Catholic cemeteries in New Orleans, Louisiana. All of these graves are above ground vaults; most were constructed in the 18th century and 19th century. Doug Keister, author/photographer of Going Out in Style: The Architecture of Eternity states that The custom of above-ground burial in New Orleans is a mixture of folklore and fact. The vaults are in fact more due to French and Spanish tradition than they are to water table problems.
