The John Lide Hart Cottage, located at 116 East Home Avenue, is the only known structure remining from John Hart's plantation. John Hart, the third son of Hartsville founder, Thomas Hart, purchased 491 acres of virgin pine forest in 1845. He established the Hartsville Plantation on the land and went on to build a carriage factory, a steam-powered saw mill, grist mill, workers' homes, a store, a post office, a school and a church. The cottage, which remains from the Hartsville Plantation, is an example of federal architecture as influenced by the vernacular cottage style prevalent in the South during antebellum times. It is completely furnished and open to the public on the first Sunday of the month, February through December.
