The 1883 Charles H. Dickinson Survey of several parishes of Louisiana shows the White Castle Plantation property.

White Castle was established as a town in the 1880s with the influx of people and business brought by the logging industry in the cypress swamps of the area.

When the cypress wood was depleted, the main economic activity reverted to the sugar cane industry which had been established in the latter part of the 18th century.

People living in the unincorporated areas of Samstown, Lone Star, Belle Grove, Dorseyville, and as far away as Bayou Goula helped support White Castle businesses through the years.

Engolio's Maggio's, Chiaramonte, Dominic Sciortino, Tina's, Forte's, and Landry's were used for grocery shopping.

During the 1950s, the chemical industry entered the area, congregating around the Mississippi River between Baton Rouge and New Orleans.

White Castle is located in southeastern Iberville Parish at 30°10′7″N 91°8′48″W / 30.16861°N 91.14667°W / 30.16861; -91.14667 (30.168503, −91.146708),[5] on the south bank of the Mississippi River.

According to the United States Census Bureau, the town of White Castle has a total area of 0.73 square miles (1.9 km2), of which 1.9 acres (7,876 m2), or 0.41%, are water.

White Castle is home to Cora Texas Sugar Mill, one of the largest in the United States.
