Cane River National Heritage Area in northwestern Louisiana is a largely rural, agricultural landscape known for its historic plantations, its distinctive Creole architecture, and its multi-cultural legacy. Historically this region lay at the intersection of French and Spanish realms in the New World. Today it is home to a unique blend of cultures, including French, Spanish, African, American Indian, and Creole. The central corridor of the heritage area begins just south of Natchitoches, the oldest permanent settlement in the Louisiana Purchase, and extends along both sides of Cane River Lake for approximately 35 miles. The heritage area includes Cane River Creole National Historical Park, seven National Historic Landmarks, three State Historic Sites, and many other historic plantations, homes, and churches. While much of the roughly 116,000-acre heritage area is privately owned, many sites are open to the public.

Located in northeastern Louisiana, this park commemorates a culture that thrived during the first and second millennia B.C. This site, which contains some of the largest prehistoric earth works in North America, is managed by the state of Louisiana.
