Fort Louis de la Mobile (Mobile, Alabama)
Mobile · Alabama · French Colonial Period

History & Significance
Fort Louis de la Louisiane was established in January 1702 by Pierre Le Moyne d'Iberville and placed under the leadership of his brother Jean-Baptiste Le Moyne de Bienville. The fort was a square structure with corner bastions, each armed with six cannons, and included living quarters, a chapel, and a warehouse.
The colonists laid out a street grid centered on their fort, the first formal European-style town plan on the Gulf Coast. The settlement served as the economic and political center of the colony, with traders routinely traveling to neighboring tribal villages and delegations attending annual conferences at the fort; Canadian voyageurs traded Native American slaves, furs, skins, and foodstuffs for European-made goods.
In spring 1711, a catastrophic flood forced soldiers and citizens to seek safety in trees, with houses submerged to their roofs for nearly a month—the ultimate factor in relocating the settlement. When the French abandoned the site, the fort and houses were burned; archaeological evidence indicates all structures were destroyed in place. The site was listed in the National Register of Historic Places on May 6, 1976, and determined eligible for designation as a National Historic Landmark on January 3, 2001.
