Declared a National Historic Landmark in 2006, Carrie, as it’s affectionately known, entices visitors to marvel at the scale and legacy of its industrial might.  A remnant of the legendary U.S. Steel Homestead Steel Works, the Carrie Blast Furnaces are a vestige of Pittsburgh’s 20th-century domination of the steel industry.

During this two-hour guided tour, you’ll hear stories about the site’s technology (including why it is nationally significant) as well as get to know the culture of its workers. You’ll also learn a bit about the iron-making process, from the movement of the raw materials to the tapping of the furnaces that produced fiery molten iron.
