Not quite correct.
Beauvoir, the post-Civil War home of Jefferson Davis, was still standing after Katrina -- although it did suffer very heavy damage. I think it may have done better than any other home along that stretch of beach. And it was one of three homes there to have escaped major damage from Hurricane Camille in 1969.
All of which goes to show that construction tradesmen built sturdier houses back in the 19th century than they build today!
