A time capsule back to the Civil War era, Tannehill Ironworks in Central Alabama is the site that produced much of the iron for the Confederate Army's ordnance. Along with the remains of old furnaces, you can visit the Iron & Steel Museum of Alabama, a grist mill and a cotton gin house. The furnaces were attacked and burned by Union forces on March 31, 1865. The park also has over 17 miles of trails for hiking and biking.
