It also contends the archaeological remains may yield information about mining technology and the daily lives of miners.","narrative":"Cairnbrook is a coal mining village and extractive site in central Shade Township, Somerset County, laid out in 1912 by S.E. Dickey & Company of Johnstown for the Loyal Hanna Coal and Coke Company of Philadelphia. The company built about 200 houses on a 45-degree grid, along with a company store, office, school, church and water plant, and separated managers' housing on First Street from workers' housing elsewhere. Loyal Hanna Mine Number 6, a double drift entry worked from 1914 in the 50-inch Lower Kittanning seam, sits nearby, and its surviving mule barn, motor barn, supply house, substation and oil house are built of fieldstone, brick and hollow tile. Production ran until March 1958, when exhaustion of the coal closed the mine. The district is valued for preserving the layout and buildings of a planned coal town, and for the archaeological remains that may document mining technology and miners' working lives.","period_of_significance":"1912-1943","architect_builder":"Dickey, S.E., and Company (civil and mining engineers, Johnstown)","architectural_style":"Prairie School","criteria":["A","C","D"],"status_note":"The mine ceased production in 1958 and the extractive buildings were later used by a lumber company; the document states that several resources were razed and some non-contributing buildings were added.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:35.955911-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/94000523.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/94000523/7477860627-800.webp","url_1600":"https://nationalhistoricalregister.com/media/94000523/7477860627-1600.webp","licence":"Public domain","author":"Jet Lowe","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Loyalhanna_Coal_and_Coke_Company_Office,_Cairnbrook.jpg\" rel=\"noopener\">Jet Lowe</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Loyalhanna_Coal_and_Coke_Company_Office,_Cairnbrook.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71993873","wikipedia":"https://en.wikipedia.org/wiki/Cairnbrook_Historic_District","wikidata":"https://www.wikidata.org/wiki/Q5017678"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/somerset-county/cairnbrook-historic-district-94000523/"}
