It also cites the links between the mill and the railroad, the early colonial family owners, and its relationship to the nearby Concordville Historic District.","narrative":"Begun in 1704 by Nathaniel Newlin, an Irish Quaker who had reached Pennsylvania in 1683, this complex in Concord Township near Concordville centres on a water-powered grist mill beside Chester Creek. A datestone in the wall carries the 1704 date and the initials of Newlin and his wife. Nearby stand a two and one-half story warehouse, a rubble-stone Miller's House dated to 1739, a Trimble House built in two sections, and a Spring House from 1740 that was moved to the site. A railroad station linked the mill to Philadelphia and Baltimore markets. The mill ran until 1940 and was restored about fifteen years later. It is valued for its architecture and for tracing milling and commerce across a century and a half in a region of early mills. Two trees on the grounds are said to date from William Penn's time. The land is a non-profit historic park open to visitors.","period_of_significance":"1704-1870","architect_builder":"Nathaniel Newlin (1665-1729)","architectural_style":"Victorian pointed or Gothic style (railroad station); Delaware County eighteenth century architectural style (mill and houses)","criteria":[],"status_note":"Mill operated until 1940, was restored about fifteen years later, and has since been part of a historic park; the mill grinds corn as a demonstration for visitors.","vacant_flag":false,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:34.125429-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/83002240.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/83002240/99d40255eb-800.webp","url_1600":"https://nationalhistoricalregister.com/media/83002240/99d40255eb-1600.webp","licence":"Public domain","author":"User:Smallbones on English Wikipedia.","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:NewlinMills3.JPG\" rel=\"noopener\">User:Smallbones on English Wikipedia.</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:NewlinMills3.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71995671","wikipedia":"https://en.wikipedia.org/wiki/Newlin_Mill_Complex","wikidata":"https://www.wikidata.org/wiki/Q15262162"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/delaware-county/newlin-mill-complex-83002240/"}
