Designated a National Historic Landmark in 1970, it is located on River Road on the west bank of the Mississippi River in St. Charles Parish. Constructed between 1787 and 1791 and lived in until fairly recently, it is falling to the ravages of time.
I just saw this comment today. I took that picture for a descendant of the original owners. She was living in Michigan. I noticed someone had been doing some work on the house when I was there in July 2010. The stairs had been moved from the center to the right side:http://www.pbase.com/jperilloux/image/128525830
