The district has 183 resources, 127 contributing and 56 noncontributing, and was first erected by the Berwind-White Coal Mining Company between 1902 and 1905.","why_significant":"The district is significant for industry and community planning and development. Eureka No. 40 was one of Berwind-White's most productive mines and its mine technology served as a regional model. The associated patch community reflects common features of Pennsylvania coal towns, with cheaply built, similar houses and a clear hierarchy separating management from labor.","narrative":"Begun in 1905 on farmland in southern Cambria County, the Eureka No. 40 mine and its surrounding patch town were built by the Berwind-White Coal Mining Company, with the houses constructed through its subsidiary, the Windber Lumber Company. The mine site sits on the creekside flats of Little Paint Creek, with a brick powerhouse completed in 1906 and a coal cleaning plant rebuilt in 1928 and expanded in 1941. The mine was among the company's most productive, reaching a peak of 767,921 tons in 1913, and its ventilation and power systems were regarded as advanced for their time. Patch houses were built in rows of identical double dwellings on a grid of streets up the hillside, typical of company towns across western Pennsylvania. The district is significant for its industrial technology and for its community planning, and it retains many of its mine buildings and worker houses, though some have lost original siding and windows.","period_of_significance":"1905-1942","architect_builder":"Windber Lumber Company","architectural_style":null,"criteria":["A"],"status_note":"The mine closed in 1980 and the site has been vacant since, except for a small steel fabricating business in the former power house building.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:36.440759-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/92000392.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/92000392/0143ef57d3-800.webp","url_1600":"https://nationalhistoricalregister.com/media/92000392/0143ef57d3-1600.webp","licence":"Public domain","author":"Jet Lowe","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Sand_tank_at_Eureka_No._40.jpg\" rel=\"noopener\">Jet Lowe</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Sand_tank_at_Eureka_No._40.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71998049","wikipedia":"https://en.wikipedia.org/wiki/Berwind-White_Mine_40_Historic_District","wikidata":"https://www.wikidata.org/wiki/Q4896030"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/cambria-county/berwind-white-mine-40-historic-district-92000392/"}
