The Beauvoir estate, built in Biloxi, Mississippi, along the Gulf of Mexico, was the post-war home (1876–1889) of the former President of the Confederate States of America, Jefferson Davis. The house and plantation have been designated as a National Historic Landmark, recognized and listed by the U.S. Department of the Interior and its National Park Service. At that time, the main house was adapted as a house museum. In 1998, a library was completed and opened on site.
