This National Historic Landmark was the residence of two of Louisiana's foremost political figures, Edward Douglas White, who was governor from 1835 to 1839, and his son, Edward Douglass White, who was appointed to the U.S. Supreme Court in 1894 and served as chief justice from 1910 to 1921.

Today, an exhibit tells the story of the Bayou Lafourche area, with sections on the Chitimacha Indians, Acadian settlers, sugarcane plantations, slavery, and the White family.

Madame John's is an excellent example of Louisiana Creole residential design at the end of the 18th century. Because of its fine architectural character, it has been designated as an official National Historic Landmark. The architectural complex at Madame John's actually consists of three buildings: The main house, the kitchen with cook's quarters, and the two-story garconniere.

Today, the main house has been restored and is open to the public.

The Upper and Lower Pontalba Buildings, which make up the 1850 House, were built by the Baroness Micaela Almonester de Pontalba, the daughter of Don Andres Almonester y Roxas, the Spanish colonial landowner associated with the neighboring Cabildo, Cathedral, and Presbytere. Inspired by the imposing Parisian architecture the Baroness favored, the rowhouses were intended to serve as both elegant residences and fine retail establishments.

To illustrate the landmark's historical significance, the State Museum has recreated what one of the residences would have looked like during the Antebellum era when the Baroness Pontalba first opened her doors. Furnished with domestic goods, decorative arts, and art of the period, the 1850 House depicts middle-class family life during the most prosperous period in New Orleans's history. Limited docent- and curator-led tours are available, as is self-directed viewing.

Renowned French Impressionist paintings—four by Claude Monet, three by Edgar Dega—and notable works by Édouard Manet, Mary Cassatt, and James McNeill Whistler are highlights of the Museum's in situ exhibition. The 152-acre property features an Arts and Crafts carriage barn and theater, stone garages, woodland trails, a pond and dairy complex, and a Sunken Garden designed by Beatrix Farrand c. 1920.

The museum offers exhibits, tours, research library access, educational programs, and recreational and educational events.

The Sanchez Adobe was constructed between 1842 and 1846 by Francisco Sanchez, owner of Rancho San Pedro and one-time alcalde of San Francisco. Sanchez was a leader of Mexican California who led volunteers against United States forces at the Battle of Santa Clara. Today, the site shows the different periods of local history. Visitors can take a walk on the grounds and see native plants—the Ohlone village of Pruristac was located on the site. They can view the location of the original Spanish farm buildings; explore the Sanchez family's adobe home; and discover what items were uncovered during archaeological digs, including items from the adobe's time as a hotel and speakeasy.
