Plaquemine Lock State Historic Site

Learn about the lock and waterway that helped bring trade and prosperity to much of Louisiana. In 1909, the Plaquemine Lock was once considered a feat of engineering, lifting boats and barges 51 feet. Today, the lock structure and lockhouse are on the National Register of Historic Places. The lockhouse serves as a museum and visitor center. Visitors to the site will have a chance to see the lockmaster’s house as well as watercraft that would have once used the lock.
