The West Baton Rouge Museum houses the only permanent collection of objects, photos, documents, and art that chronicle the history and culture of the entirety of West Baton Rouge Parish and the ways in which the parish relates to the state, national, and global history. Collection items range in date from the late 18th century to modern time. The permanent collection is owned by the West Baton Rouge Historical Association and supports the museum's primary interpretive themes, which include rural life and urban development in West Baton Rouge Parish, sugar plantation history, and local folklife.
