Helena played an important part in the Civil War history of Arkansas. Fort Curtis, a Union fort the size of a city block, is open for tours and events. Interpretive wayside panels are at locations throughout the town. Freedom Park includes exhibits that explore the African-American experience in Civil War Helena. The exhibits follow the journey of the African-Americans from fugitive slave to freedom; and for some, enlistment in the Union Army and participation in the Battle of Helena on July 4, 1863. Freedom Park has been designated as a part of the National Park Service's National Underground Railroad Network to Freedom. Additional interpretation will be added throughout Arkansas's Civil War Sesquicentennial.
