The document states it was first constructed around 1690 and has been enlarged since.","why_significant":"The nomination argues the mill is significant as an early stone grist mill associated with Jasper Farmar, an early settler of the Whitemarsh area, who is said to have served as an interpreter at Peace Councils held with local Indians. The mill is described as having remained in operation for approximately 200 years.","narrative":"Farmar's Mill is a three-story grist mill of dressed fieldstone with a gabled roof that extends below the second-story windows, standing beside the Wissahickon Creek in Fort Washington, Montgomery County. It was built on land within a 5000-acre tract purchased from William Penn in 1683 by Jasper Farmar, a British Army major who died before emigrating. His widow Mary and son Edward inherited the acreage, and the family arrived in Philadelphia in 1685. Farmar built the stone mill between 1685 and 1700, and it operated for roughly two centuries. The mill is significant for its early construction, its long working life, and its association with Farmar, who became an interpreter at Peace Councils held with local Indians. The building has been enlarged since it was first constructed and remains on its original site.","period_of_significance":"1685-1700","architect_builder":null,"architectural_style":null,"criteria":["A"],"status_note":"Condition is marked fair and the structure is marked unaltered with its original site retained, though it has been enlarged over time.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:29.729796-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/72001140.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/72001140/c916ed6fc5-800.webp","url_1600":"https://nationalhistoricalregister.com/media/72001140/c916ed6fc5-1600.webp","licence":"Public domain","author":"Smallbones at English Wikipedia","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:MathersMillPA.JPG\" rel=\"noopener\">Smallbones at English Wikipedia</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:MathersMillPA.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71995600","wikipedia":"https://en.wikipedia.org/wiki/Farmar_Mill","wikidata":"https://www.wikidata.org/wiki/Q526926"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/montgomery-county/farmar-mill-72001140/"}
