Always more to learn: Tannehill Ironworks Historical State Park, AL

The restored blast furnaces of the Tannehill Ironworks rise high above Roupes Creek.

Writing a travel book can be full of surprises. When I set out, I had no inkling that I would be learning about the early iron-making industry. During the Civil War, Alabama played a key role in producing pig iron (more than all of the other Confederate states combined) and making cannons and ammunition. Bars of pig iron were sent to the Selma Arsenal, which produced half of the cannon and two-thirds of the ammunition used by the South in the final two years of fighting. This region is unique in the world for its abundance of all of the resources needed for iron production: iron ore, limestone, and either coal to make coke or forests to produce charcoal.

Hikes in the park at times follow an old stagecoach route or the Iron Road where the pig iron was transported 18 miles by eight team mule wagons to the Alabama & Tennessee Rivers Railroad.

Spotted trillium (or perhaps the look-alike Little Sweet Betsy) in a wet swampy spot near Roupes Creek. During my week at Tannehill, the woods began to green up, with flowering dogwood, redbud, and native azaleas adding touches of white, lavender, and pink.

Violets bloom in an old slave cemetery, brightening the final resting places of furnace workers and their family members, whose names are long forgotten.

Tannehill is also home to the Alabama Iron and Steel Museum, which surpassed all my expectations. For almost two hours, the story of Tannehill came to life for me. Beginning with the huge seams of brown and red iron ore found locally, to colliers camping in huts to make charcoal to large displays of 1800s household and military items made either here or at the Selma Arsenal.
