Oak Valley Plantation

Oak Valley Plantation is a restored, antebellum manor house and plantation in Vacherie, Louisiana, on the Mississippi River between New Orleans and Baton Rouge. It was not severely damaged by Hurricane Katrina, but their tourist revenue has been greatly diminished by the economic disaster now facing the Gulf Coast. There are, of course, more grievous concerns still facing the region, but the non-profit Oak Alley Foundation has established the Oak Alley Plantation's Hurricane Katrina Economic Disaster Fund to help keep up the maintenance of the landmark until the area's economic situation improves.
