Travelers along the southern portion of the Great River Road will find a bevy of historical sites and attractions, but antebellum homes—massive, ornate pre-Civil War properties that sit along the Mississippi River—are some of the South’s most interesting attractions. Here are three you shouldn’t miss.

Lakeport Plantation, Lake Village, Ark.

Lakeport Plantation is the only remaining Arkansas antebellum plantation on the Mississippi River. The home now serves as a museum and educational center teaching visitors about the Johnson family (who occupied the home until 1927), as well as the cotton industry and other historical events that affected residents in the Lake Village area.

Dunleith Historic Inn, Natchez, Miss.

Before the Civil War, the river town of Natchez, Miss., was home to more millionaires per capita than any other city in the United States. Many of these wealthy residents’ impressive homes are now open to visitors for tours or even overnight stays, including the Dunleith Historic Inn. Dunleith, recently seen in the James Brown biopic “Get on Up”, was built in 1856 and sits on 40 beautifully landscaped acres. Several buildings on the property date back to the 1790s, including the carriage house and stables, and a dairy barn.

Nottoway Plantation, White Castle, La.

The largest remaining antebellum home in the South, the Nottaway Plantation House is a staggering 53,000 square feet and contains 64 rooms, seven staircases and five galleries. Built along the banks of the Mississippi River in 1858, the home also features an impressive ballroom painted in all white (including the floor). The plantation has recently undergone a multi-million-dollar renovation now features a resort with 40 overnight rooms, a restaurant, and more.
