Fort De La Boulaye Site, also known as Fort Mississippi, is the site of a fort built by the French in south Louisiana in 1699–1700, to support their claim of the Mississippi River and valley. Native Americans forced the French to vacate the fort by 1707. The site was declared a National Historic Lan
dmark in 1960, as part of the history of French colonization of the area. The state of Louisiana had earlier erected an historical marker, with the following text: FORT de la BOULAYE First white settlement in present-day Louisiana, erected by Bienville in 1699 on this spot (then the bank of the Mississippi), prevented Britain's seizure of the Mississippi Valley.
