This raised center hall house was built in 1826, for wealthy auctioneer Joseph LeCarpentier. Named for two famous former residents, the Confederate general Pierre Gustave Toutant (P.G.T.) Beauregard and the author Frances Parkinson Keyes, it is also the birth place in 1837 of master chess player Paul Morphy (the grandson of LeCarpentier)

General Beauregard lived in the home after the defeat of the Confederacy from 1866-68. Mrs. Keyes used the home as her winter residence for 25 years until her death in 1970.  She wrote many of her books here, including Dinner at Antoine’s, The Chess Players, Madame Castel’s Lodger (inspired by General Beauregard stay in the house) and Blue Camellia.  Mrs. Keyes left her home and collections of antique dolls, teapot , fans and folk costumes to a foundation so that the public could enjoy the house and gardens.
