Pittsburgh Steel City

About the Steel City

Pittsburgh is a major city in Pennsylvania, known for its steel industry heritage, the iconic Three Rivers confluence, and modern transformation. The city combines industrial history with contemporary innovation, featuring the University of Pittsburgh, Carnegie Mellon University, and world-class museums.

The nickname "Steel City" grew out of Pittsburgh's dominance of American steelmaking in the late nineteenth century, when Andrew Carnegie opened the Edgar Thomson Steel Works at Braddock in 1875 and U.S. Steel was incorporated in 1901 with Pittsburgh-area mills at its core. By the early twentieth century the region produced a large share of the nation's steel, and labor history there, including the 1892 Homestead strike, became nationally known. Most mills shut in the late 1970s and 1980s, with the Homestead Works closing in 1986, and the local economy shifted toward health care, universities and technology. The label survives mainly in local identity, the U.S. Steel Tower and the Pittsburgh Steelers, named in 1940.
