The house and mill were built around 1814 by Jacob Keller.","why_significant":"The house is presented as an excellent example of a Federal and Germanic style Pennsylvania farmhouse and one of only three such houses surviving in Ephrata. Its two Indian doors, which can be slid to conceal the glazing and present a solid wooden appearance, are described as seldom found in Lancaster County today. The farm is also tied to the Keller family's early eighteenth-century land holdings.","narrative":"Near Ephrata, on Rettew Mill Road, stands a two-and-a-half-story limestone farmhouse begun in 1814 and marked by paired date stones bearing the names of Jacob and Alicesabeth Keller. Its five-bay facade has nine-over-six sash, and an 1856 frame wing was added to the west. The house is regarded as a fine example of the Federal and Germanic farmhouse once common across Lancaster County, and one of only three such houses surviving in Ephrata. Its two Indian doors, which could be slid to cover the glazing and present a solid wooden face, are seldom found in the county today. Interior woodwork, including a corner cupboard and a second-floor fireplace mantle, survives in good condition. Across the road stand the stone foundation of a barn and a stuccoed stone mill, the third on the site, both dating to about 1814.","period_of_significance":"1814-1856","architect_builder":"Jacob Keller","architectural_style":"Federal and Germanic","criteria":[],"status_note":"The house is in excellent condition; the mill is vacant and has deteriorated, and the barn was destroyed by fire in December 1984.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:13:28.701976-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/86001679.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/86001679/0a42a6ad3b-800.webp","url_1600":"https://nationalhistoricalregister.com/media/86001679/0a42a6ad3b-1600.webp","licence":"CC BY-SA 3.0","author":"JERRYE &amp; ROY KLOTZ MD","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:JACOB_KELLER_FARM,_LANCASTER_COUNTY,_PA.jpg\" rel=\"noopener\">JERRYE &amp;amp; ROY KLOTZ MD</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:JACOB_KELLER_FARM,_LANCASTER_COUNTY,_PA.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71995487","wikipedia":"https://en.wikipedia.org/wiki/Jacob_Keller_Farm","wikidata":"https://www.wikidata.org/wiki/Q6118851"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/lancaster-county/keller-jacob-farm-86001679/"}
