Sloss Furnaces is a preserved 19th-century pig iron manufacturing facility that functioned from 1882 to 1971. It is the only twentieth-century blast furnace site in the United States being preserved and interpreted as an industrial museum. The site features a labyrinth of pipes, boilers, and smokestacks covering several acres. It now serves as a community center for metal arts, including iron pouring and blacksmithing workshops. The grounds are designated a National Historic Landmark, recognized for their role in Birmingham's rapid industrialization. Visitors can explore the maze of iron structures via self-guided walking paths. The site hosts regular industrial arts demonstrations and rotating public events.
