St. Bernard Parish: A History of Resilience and Heritage

Located in the southeastern corner of Louisiana, St. Bernard Parish is a region defined by its intimate relationship with water and its enduring spirit of recovery. Founded on March 31, 1807, and named after Bernardo de Galvez, the parish serves as a gateway between the Mississippi River and the Gulf of Mexico. From its role in pivotal American military history to its struggle against catastrophic natural disasters, St. Bernard is a land of profound contrasts and deep cultural roots.

Today, the parish is centered around its seat, Chalmette, and is characterized by a landscape where land and water are inextricably linked. While it has faced immense challenges, it was the fastest-growing parish in Louisiana between 2010 and 2020, signaling a steady return to growth and stability.

Historical Milestones

The Battle of New Orleans

The crown jewel of the parish's historical attractions is the Chalmette Battlefield, part of the Jean Lafitte National Historical Park and Preserve. This site hosted the Battle of New Orleans on January 8, 1815, during the War of 1812. The influence of this event persists today; many local streets are named after the battle's participants or follow a pirate theme in honor of Jean Lafitte, who is remembered as a hero of the conflict. General Andrew Jackson, the commanding officer of the defense, is also honored through local educational institutions.

Kenilworth Plantation House (originally Bienvenu) in St. Bernard's Terre aux Boeufs dates back to the 1750s.

The Great Mississippi River Flood of 1927

In 1927, a catastrophic flood led New Orleans and state officials to make a controversial decision: they used dynamite to breach a levee at Caernarvon to relieve pressure and save the city of New Orleans. While residents of the city initially believed this action was necessary, historians now suggest the breach was unnecessary due to upstream breaks. The result was widespread destruction across Eastern St. Bernard Parish and parts of Plaquemines Parish, with residents never receiving adequate compensation for their losses.

The Impact of Hurricane Katrina and Hurricane Ida

On August 29, 2005, Hurricane Katrina devastated the parish. A 25-foot storm surge entered through the Mississippi River Gulf Outlet (MRGO), destroying levees and flooding nearly the entire parish with 5 to 15 feet of water. Many homes were completely washed off their foundations.

The recovery was a monumental effort. Organizations like the H.O.P.E. Project, Camp Hope, and the St. Bernard Project emerged to provide tools, housing for volunteers, and direct assistance to residents. Despite the devastation, key industrial hubs like the ExxonMobil plant in Chalmette and the Domino Sugar plant in Arabi returned to operation by December 2005.

More recently, on August 29, 2021, Hurricane Ida brought heavy flooding to the region. Despite warnings of an 11-foot storm surge, local officials opted not to issue a formal evacuation order, though the parish once again faced the challenges of severe weather.

Geography and Environment

St. Bernard Parish is a landscape of alluvial lands—soil deposited by flowing water—and numerous small islands. It is the second-largest parish in Louisiana by total area, though only 378 square miles is land. The region is defined by the Bayous Terre aux Boeufs and La Loutre, and its natural canopy is dominated by the bald cypress tree.
