The district contains roughly 326 resources, including the Shupe Steam Grist Mill, the Penn Theater and numerous brick commercial blocks.","why_significant":"The nomination argues the district is significant for commerce as a locally important center serving surrounding agricultural areas, company towns, coal and coke industries and the railroad, and for architecture because of its range of styles from the early nineteenth century through the early twentieth century. It notes that Mount Pleasant grew along the Glades Road and the Somerset and Mount Pleasant Turnpike and was incorporated as a borough in 1828.","narrative":"Mount Pleasant is a borough in southern Westmoreland County whose historic district follows Main Street and the side streets that run south from it. Brick buildings erected around 1812 along Main Street are among the earliest surviving in the area, and the town was incorporated in 1828. Commercial blocks from the 1870s to 1910 use red and yellow brick, corbeled cornices and sandstone lintels, and include the Citizens Savings and Trust Company, a Classical Revival bank of 1905. The Shupe Steam Grist Mill dates from about 1843 and still operates with its original steam machinery. Henry Clay Frick worked as a young man in his uncle Martin Overholt's general store on Main Street. The district is also valued for its churches, including Gothic and Romanesque brick buildings from the late 1860s to about 1910, and for the Penn Theater, a 1937 Art Deco building. Together these resources show the town's growth as a local commercial center tied to coal, coke and rail.","period_of_significance":"c. 1812-1948","architect_builder":"Bowers, Robert; Cooper, Andrew P.; Harmon, John R.; Jones and Walker; Simon, Louis","architectural_style":"Georgian, Italianate, Queen Anne, Colonial Revival; also Classical Revival, Art Deco, Romanesque and Gothic elements","criteria":["A","C"],"status_note":"The Shupe Mill continues to operate with original steam machinery, and the Penn Theater has been converted to a wood working shop; most of the commercial district has few vacant storefronts.","vacant_flag":false,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:37.969073-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/98000903.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/98000903/1a06fe3c91-800.webp","url_1600":"https://nationalhistoricalregister.com/media/98000903/1a06fe3c91-1600.webp","licence":"CC BY-SA 3.0","author":"Canadian2006","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Main_Street_Mount_Pleasant_Pa_2011.jpg\" rel=\"noopener\">Canadian2006</a>, <a href=\"https://creativecommons.org/licenses/by-sa/3.0\" rel=\"license noopener\">CC BY-SA 3.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Main_Street_Mount_Pleasant_Pa_2011.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71996646","wikipedia":"https://en.wikipedia.org/wiki/Mount_Pleasant_Historic_District_(Mount_Pleasant,_Pennsylvania)","wikidata":"https://www.wikidata.org/wiki/Q6922918"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/westmoreland-county/mount-pleasant-historic-district-98000903/"}
