Longfellow-Evangeline State Historic Site, State historic site and museum in St. Martinville, Louisiana.

Longfellow-Evangeline State Historic Site covers 157 acres in St. Martinville. Maison Olivier, built around 1815 by Pierre Olivier Duclozel de Vezin, is a raised Creole cottage behind the visitor center, with a blacksmith shop nearby. A c. 1790 Acadian cabin shows the contrast with Creole building, and a reproduction early 19th-century Acadian farmstead near Bayou Teche includes a house, barn, privy, outdoor kitchen and bread oven.

The land was originally used by the Attakapas people for hunting before French settlers established plantations growing indigo and later cotton. The buildings standing today date from this period of agricultural development in the 1800s.

The site's name comes from Longfellow's 1847 epic poem Evangeline, which recounts the 1755 expulsion of the Acadians from Acadia. In 1907 Judge Felix Voorhies of St. Martinville published "Acadian Reminiscences: The True Story of Evangeline," a local prose version of the tale. French remains strong in the region, and the site traces the settlement of Louisiana by Native Americans, French, Acadians, Creoles, Africans and Spaniards.

The site covers 157 acres in St. Martinville, with Maison Olivier standing behind the visitor center and a blacksmith shop nearby. A reproduction Acadian farmstead, including a family home, barn, privy, outdoor kitchen and bread oven, lies near Bayou Teche. Paths link the buildings across the grounds, so allow time to walk between them.

The Evangeline Oak in St. Martinville's town centre is named as the legendary meeting place of Evangeline and Gabriel, the lovers of Longfellow's 1847 poem. A statue of Evangeline marks her supposed grave beside St. Martin of Tours Church. The poem's story was retold locally by judge Felix Voorhies in his 1907 book "Acadian Reminiscences: The True Story of Evangeline."
