Tennessee Coal & Iron Company, Fairfield Works, North of Valley Road, west of Ensley-Pleasant Grove Road, Fairfield, Jefferson County, AL

Significance: Since its construction in 1917, the Fairfield Works has remained the largest steel mill in the southeast. Its blast furnace plant has historically featured the largest furnaces in the South and the No. 8 Furnace, the only furnace currently standing, is one of the largest in the United States. While most of the older structures and facilities have been modified or replaced, the current facilities including a seamless pipe mill, Q-BOP steel furnaces and continuous caster are all "state of the art" modern facilities.
