Mulberry Plantation, also known as the James and Mary Boykin Chesnut House is a historic plantation at 559 Sumter Highway (United States Route 521) south of Camden, South Carolina. Declared a National Historic Landmark in 2000, it is significant as the home of American Civil War chronicler Mary Boykin Chesnut, who produced some of the most important written accounts of the war from a Confederate perspective. The main house, built about 1820, is a fine example of Federal period architecture.
