Built in 1907 the Homestead Works was once a huge iron making operation on the Monongahela river near Pittsburgh, PA. Today the “Carrie 6″ and “Carrie 7″ blast furnaces are all that remain on the silent 430 acre site. Future plans will allow visitors to climb and explore the furnaces in what is expected to be a $78 million stabilization and renovation project creating the Homestead Works National Park.
