Southdown Plantation, Sugar plantation along Little Bayou Black in Houma, Louisiana

Southdown Plantation is a sugar plantation in Terrebonne Parish, Louisiana. Its main house, built in 1858 and enlarged in 1893, is made of hand-fired brick with walls painted in the original 1893 pink and green scheme. The house has two stories, Virginia-style colonnaded walkways, and tall interior spaces.

The estate was founded in the 1820s as an indigo operation before being converted to sugar production within a few years. This shift shaped the region's economy for many decades afterward.

The house is named for a breed of sheep the Minor family raised. Its 1893 Favrile glass panels depict palmetto leaves, magnolia branches and sugar cane stalks. The Minor family hosted balls and receptions here, and the museum opened on June 27, 1982.

The house and slave quarters opened as a museum on June 27, 1982, run by the Terrebonne Historical and Cultural Society, which received the property in 1975. The site sits along Little Bayou Black near Houma; check opening days before visiting, since access is by guided tour.

The house was renovated in the late 1800s with decorative stained glass panels showing local plants and scenes of the estate. These artistic elements remain in their original positions today.
