Fleming Cemetery, also known as the Berthoud Cemetery, is built on a Native American mound. The mounds and middens were used to keep below ground burials above the water table. Note that being buried above ground is not usually for water table reasons, but more cultural tradition.
Established in the 1890s with the burials of the Berthoud brothers at the top of the mound, the people Barataria began burying their dead there, often bringing them by boat. The tombs are painted brilliantly white before All Saints Day every year.
Legend has it that both Lafitte, the pirate, and Napoleon Bonaparte are buried here, though there are similar claims by some at Metairie Cemetery and several other places. More recently, it was featured in True Detective season one.
