The Home and Library of Jefferson Davis
Beauvoir is the name gives to the historic home of the President of the Confederacy, Jefferson Davis. Unfortunately, the site suffered heavily during Hurricane Katrina but has since been resorted to its prior glory and is now back open to the public. The Jefferson Davis Presidential Library was actually so damaged during the hurricane that it had to be demolished entirely and rebuilt!
The house itself, though, is back in perfect condition complete with original artifacts from the days of the Confederacy, period furniture, and plenty of photos. I'd suggest taking the guided tour as the explanations and anecdotes of the guides help bring to life what is otherwise an ordinary, if not pretty, home. One the guides put the various rooms and objects in context it actually makes for a fascinating visit.
