Nottoway Plantation
Built by slaves for John Randolph, this 1850s antebellum estate is reputed to be the South's largest and looks like it could be the White House. It functions as a hotel and restaurant but is also available for tours.

Understand
The languid streets of this town hugging the Mississippi River seem to belie its booming entrepreneurial cotton market of the past, or the ugly race riot here of 1963 where white law enforcement descended upon a group of black protesters with horses and cattle prods, trying to root out a leader of the Congress of Racial Equality (CORE) named James Farmer. But it is a tranquil setting along the river, especially when visiting its main attraction, the Plaquemine Lock, and witnessing the grandeur of water and engineering.

Designed in 1909 by Colonel George Washington Goethals, who went on to design the Panama Canal, this structure is great fun to check out even though it's no longer operating: you can walk along the precipitous edges of the lock and still imagine how freight vessels were conveyed from Bayou Plaquemine to the Mississippi River.
