It comprises about 1,693 contributing buildings and two contributing structures, with 141 non-contributing buildings.","why_significant":"The nomination argues the district is significant for its architecture, with two generations of buildings from 1890 to 1915 and from 1917 to 1930, and for its role in commerce and community planning. Charleroi was launched as a speculative real estate and industrial town in 1890 and grew into the retail and wholesale center of the Middle Monongahela Valley. The document regards the district as an extensive concentration of small houses and storefronts, with larger Classical Revival buildings added later.","narrative":"Charleroi's historic district covers about 80 percent of the borough, laid out in 1890 on a generally orthogonal street grid that climbs from the riverside flats to a steep hillside west of the Pennsylvania Railroad tracks. Most of its roughly 1,693 contributing buildings date from 1890 to World War I. They include small two-story frame houses, many of them front-gabled, and brick storefronts with pressed metal cornices. The core business area follows about five blocks of McKean and Fallowfield Avenues between Third and Seventh Streets. Larger Classical Revival and Colonial Revival buildings from 1917 to 1927 anchor the business district. The district is significant for architecture, reflecting the Queen Anne and Colonial Revival styles in scaled-down form, and for commerce and community planning. Charleroi grew from a speculative real estate venture, founded in 1890, into the main retail and wholesale center of the Middle Monongahela Valley.","period_of_significance":"1890-1957","architect_builder":null,"architectural_style":"Queen Anne; Colonial Revival; Classical Revival; Gothic Revival; Greek Revival; Late 19th and 20th Century Revivals","criteria":["A","C"],"status_note":null,"vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:10:27.218635-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/07001162.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/07001162/6841963d4d-800.webp","url_1600":"https://nationalhistoricalregister.com/media/07001162/6841963d4d-1600.webp","licence":"Public domain","author":"Nyttend","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Fallowfield_Avenue_above_Eighth_Street_in_Charleroi.jpg\" rel=\"noopener\">Nyttend</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Fallowfield_Avenue_above_Eighth_Street_in_Charleroi.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71994999","wikipedia":"https://en.wikipedia.org/wiki/Charleroi_Historic_District","wikidata":"https://www.wikidata.org/wiki/Q5074687"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/washington-county/charleroi-historic-district-07001162/"}
