This is definitely among the best of the historic homes to visit in the quarter, and one of the best values too. For under 10 bucks you can get a private tour--not bad.
The Beauregard-Keyes House was built in 1826 for wealthy auctioneer Joseph LeCarpentier and is an example of a raised center hall house. Confederate General Pierre Gustave Toutant (P.G.T.) Beauregard was a New Orleans native who ordered the first shots of the Civil War fired on Fort Sumter, South Carolina. He lived in the house 1866-1868 while he was president of the New Orleans, Jackson & Great Northern Railroad. Frances Parkinson Keyes was the distinguished author of more than fifty books and short story collections who lived and wrote here for more than 25 years, nearly a century after Beauregard.
The interior is just shy of 5,000 square feet, with 2 bedrooms, a large parlor, ballroom, and a rectangular dining room whose floor is slightly off level. Pictures of the family adorn the walls, which the tour guide did a good job of explaining. The Beauregard chambers feature many of the original furnishings used by the General and his family, including an old grand piano, hand fans, Keyes' 200+ doll collection, armoires, chests/drawers, etc.. The first bedroom is interesting, in that there is no wall behind the bed--slip behind it and enter the second bedroom just like the servants once did.
The brick-walled garden features a lovely cast iron fountain and boxwood hedges. The quarters in the back of the house is where Keyes wrote all her novels and has quite a view of the courtyard.
Definitely worth it, but if you're looking for a larger house and more extensive history check out the Hermann or Gallier House.
