Clairton, Pennsylvania is located along the Monongahela River. Incorporated on April 12, 1903, Clairton was based around Clairton Works, which became the largest coke manufacturing facility in the United States. The production of coke was vital for the pig iron blast furnaces that produced steel throughout the region.

The population of the city peaked at nearly 20,000 in 1950 and declined by 67% by 2010, mirroring the decline of the steel industry. Clairton was designated a distressed municipality in 1988 and has not recovered from its industrial might.
