Antebellum architecture (meaning "prewar", from the Latin ante, "before", and bellum, "war") is the neoclassical architectural style characteristic of the 19th-century Southern United States, especially the Deep South, from after the birth of the United States with the American Revolution, to the start of the American Civil War. Antebellum architecture is especially characterized by Georgian, Neo-classical, and Greek Revival style plantation homes and mansions.
Many plantation houses still standing are of this style, including:Barrington Hall in Roswell, Georgia
Bulloch Hall in Roswell, Georgia
Goodman-LeGrand House in Tyler, Texas
Monmouth Plantation, in Natchez, Mississippi
Myrtles Plantation, in St. Francisville, Louisiana
