About Charleroi, PA

Charleroi ( SHAR-lə-roy) is a borough in Washington County, Pennsylvania, United States, along the Monongahela River, 21 miles south of Pittsburgh. Charleroi was settled in 1890 and incorporated in 1891. The 2020 census recorded a population of 4,210. Reduced industrial activities in the region led to a decreasing population. The steel-making industry was supported by cheap transportation on the Monongahela River from upstream of Charleroi into northern West Virginia and north as well as downstream past McKeesport to the mouth of the Monongahela in Pittsburgh. Colloquially, the stretch from Charleroi north to McKeesport (historically because of press coverage of High School sports leagues), is known as the "Mon Valley," and has been extended by some to mean from the river mouth to northern West Virginia. Once dubbed "Magic City," Charleroi has in recent years seen a gradual revitalization of its business district.
