It is tied to the Reading Furnace Tract of the Quaker ironmaster William Branson, and its land was among the early partitions sold off as the tract was cleared for farming. The farm retains its rural setting and remains in agricultural use.","narrative":"Random field stone with large cover quoins forms the main house on the Lahr Farm near Elverson, Chester County, a two-and-a-half-story dwelling built in two sections. The earlier northwest section has the only cellar and a six-panel door with a transom beneath a pent roof. A large chimney in the attached addition appears older than the house and may have belonged to an earlier log building. Inside, a cooking fireplace and a large shimmer beam dominate the principal room. The grounds also include a stuccoed stone latch house with a bake oven and a bank barn with stone piers. The property is part of the Reading Furnace Tract of Quaker ironmaster William Branson. Partitioned in the early 1780s, its land passed through several owners before the Lahr family held it from 1834 until 1938. The farm is noted for its surviving original fabric and retained boundaries, and it is still worked as farmland today.","period_of_significance":null,"architect_builder":null,"architectural_style":null,"criteria":[],"status_note":"Still a productive agricultural enterprise, according to the document.","vacant_flag":false,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:29.971448-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/79002199.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/79002199/e954b2b84f-800.webp","url_1600":"https://nationalhistoricalregister.com/media/79002199/e954b2b84f-1600.webp","licence":"CC0","author":"Smallbones","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Lahr_Farm_Chesco.JPG\" rel=\"noopener\">Smallbones</a>, <a href=\"http://creativecommons.org/publicdomain/zero/1.0/deed.en\" rel=\"license noopener\">CC0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Lahr_Farm_Chesco.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71995451","wikipedia":"https://en.wikipedia.org/wiki/Lahr_Farm","wikidata":"https://www.wikidata.org/wiki/Q6473458"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/chester-county/lahr-farm-79002199/"}
