Sugarcane cultivation brought wealth to planters along Bayou Black and present-day highway 311, where a handful of plantation mansions still stand among majestic trees. The Sugar Row Plantations thrived during the decades following the end of slavery, and each operated like a working town with sugar houses, company stores, outbuildings, gardens, and rows of workers' cabins surrounded by sugarcane fields, while the mansions fronted the bayou. Southdown Plantation's mansion in Houma features museum exhibits and historically furnished rooms, and its house, built c. 1859, shows how the sugar industry shaped the history of Terrebonne Parish. Ardoyne Plantation, built c. 1894, has been owned by the Shaffer family for six generations, and its Victorian gothic-style interior includes a hand-painted staircase, period furnishings, and family heirlooms; workers there used tokens redeemable only at the company store, now The Old Green Store. Magnolia Plantation, built c. 1855 in the Greek Revival style, stands five miles north on 311, and Crescent Farm, built by William Shaffer in 1849 three miles south on 311, produced sugar until the 1920s.
