La Balize, Louisiana was a French fort and settlement near the mouth of the Mississippi River, in what later became Plaquemines Parish. The village's name meant "seamark." La Balize was historically and economically important for overseeing the river. It was rebuilt several times because of hurricane damage. The active delta lobe of the river's mouth is called the Balize Delta, after the settlement, or the Birdfoot Delta, because of its shape.
