Want to know what Pittsburgh looked like during its steel industry days? Get a glimpse of our region’s industrial past at the Carrie Blast Furnaces National Historic Landmark — stretching between Rankin and Swissvale and towering 92 feet above the Monongahela River. The furnaces, built in 1884, are a remnant of the U.S. Steel Homestead Steel Works and a rare example of both 20th century steel dominance and pre-World War II iron-making technology.

Who Is Carrie?

For years, locals wondered about the furnaces’s namesake. In 2023, she was finally found: Carrie Clark, the daughter of William Clark, a key figure in Pittsburgh’s iron industry. She “lit the fires and performed other baptismal services,” according to a 1884 Pittsburgh Daily Post article.
