Janney Furnace Park is a park surrounding a fifty-foot tall stone furnace in Ohatchee, Alabama. The furnace was built in 1863 by Alfred Janney to produce pig iron due to the prevalence of iron ore in what is now the park. The furnace was still under construction when it was almost completely destroyed by Union troops commanded by General Rousseau in July 1864. The stone chimney of the furnace still remains. The furnace is now surrounded by the Calhoun County Confederate Memorial and the Confederate and Native American Museum, which includes Civil War and Native American artifacts dating back to the Iron Age. The Confederate Memorial is the world's largest black granite confederate memorial. The furnace was listed on the National Register of Historic Places in 1976.
