Oak Alley Plantation in Vacherie, Louisiana, is a historic Mississippi River estate named for its double row of southern live oaks, planted in the early 18th century and still its defining feature. Established for sugarcane after Valcour Aime bought the land in 1830, the property passed to Jacques Télesphore Roman, whose enslaved laborers built the present Greek Revival mansion from 1837 to 1839. The plantation is also significant for Antoine’s 1846 grafting of a thin-shelled pecan later known as the Centennial pecan. After decline following the Civil War, the estate was restored in the 20th century and eventually opened to the public.
