Rivers of Steel: Carrie Blast Furnaces National Historic Landmark

Two rusted steel furnaces rise ninety-two feet above the banks of the Monongahela River, the last of their kind remaining in a region once defined by iron and steel. Built in nineteen oh seven, these structures produced molten iron for the legendary Homestead Steel Works, feeding a machine that employed thousands and fueled American industry for decades. They are constructed of two-and-a-half-inch-thick steel plate lined with refractory brick and represent a rare, surviving example of pre-World War Two iron-making technology.
