Oaklawn Manor is at 3296 E. Oaklawn Dr. This 1837 Greek Revival mansion was the center of one of the area's first sugarcane plantations. A virtual fortress, it has 20-inch-thick walls. Inside is an extensive collection of rare prints and oil paintings by John James Audubon and an assortment of hand-painted carvings of waterfowl that winter in southern Louisiana. The manor grounds were fashioned after the gardens of Versailles.
