It was built c. 1808-1810 and is associated with the New Geneva Glassworks.","why_significant":"The nomination argues the house is significant in the area of industry because it is associated with the early glass industry of southwestern Pennsylvania. It is described as one of few surviving houses linked to that industry and as a rare survivor of the early glass works. Its original section was built by the glassworks company, and it retains enough of its early nineteenth-century form to convey that period.","narrative":"Built around 1808 to 1810 as a three-bay, two-and-a-half story log house in the village of Glassworks, north of Greensboro, Pennsylvania, this residence was laid out in a two-thirds Georgian plan with back-to-back corner fireplaces. Its hand-hewn oak logs were originally sheathed with planks, and the house rests on a rubblestone foundation. The original section was built by the New Geneva Glassworks Company, which had moved its operations to the Greensboro area in 1807 to use nearby coal. The house is linked to that company and its workers, and it is regarded as one of few surviving houses associated with the early glass industry of southwestern Pennsylvania. Its attic retains early features, including a board-and-batten door, hewn logs with stone and mud chinking, and numbered tapered oak rafters. Despite later alterations such as aluminum siding and interior panelling, it still conveys the character of an early nineteenth-century vernacular house.","period_of_significance":"C 1810 - C 1860","architect_builder":null,"architectural_style":"Georgian two-thirds plan; vernacular log house","criteria":["A"],"status_note":"Altered with aluminum siding, modern windows, interior panelling and removed partitions, but retains its historic form and feeling.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:36.666987-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/95000120.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/95000120/c9bc5b3aad-800.webp","url_1600":"https://nationalhistoricalregister.com/media/95000120/c9bc5b3aad-1600.webp","licence":"CC BY-SA 3.0","author":"Generic1139","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Glassworks-Gabler_House_Lot.jpg\" rel=\"noopener\">Generic1139</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:Glassworks-Gabler_House_Lot.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71992989","wikipedia":"https://en.wikipedia.org/wiki/Glassworks-Gabler_House","wikidata":"https://www.wikidata.org/wiki/Q5567195"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/greene-county/glassworks-gabler-house-95000120/"}
