It consists of a house, barn, kennels and associated outbuildings, and was built by Richard I. Downing after he acquired the tract in 1842.","why_significant":"The nomination argues the farmstead is a well-preserved example of a mid-nineteenth century farm complex with clear agricultural significance, one of the last relatively intact farms along the Lancaster Turnpike. The house follows a traditional four-room, double-pile, center-hall plan and retains an early Victorian interior with black marble fireplace surrounds and parquet floors. The stone and frame bank barn, with its bridge entrance, is described as a variant not common in the area.","narrative":"Colebrook Manor is a farm complex near the Lancaster Turnpike in West Whiteland Township, Chester County, Pennsylvania, with a core house dating to the mid-1800s. Richard I. Downing acquired the 130-acre tract from John Roberts in 1842 and probably built the house soon after, and it served as his principal residence while he farmed about 700 acres across West Whiteland and East Caln townships. The two-and-a-half-story stuccoed stone house has a double-pile plan, a veranda with decorative wrought iron columns, and triple-sash six-over-six windows. Its interior includes black marble fireplace surrounds, fluted window reveals and a parquet hall floor. The stone and frame bank barn, entered by a bridge, is a variant not common in the area. The property is regarded as a well-preserved example of a mid-nineteenth century farm complex and is still in agricultural use.","period_of_significance":"1840-1859","architect_builder":null,"architectural_style":"Vernacular","criteria":["C"],"status_note":"Still in agricultural use 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 17:11:33.651336-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/84003239.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/84003239/a6abb79038-800.webp","url_1600":"https://nationalhistoricalregister.com/media/84003239/a6abb79038-1600.webp","licence":"Public domain","author":"Smallbones","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Colebrook_Chesco.JPG\" rel=\"noopener\">Smallbones</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Colebrook_Chesco.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71992520","wikipedia":"https://en.wikipedia.org/wiki/Colebrook_Manor","wikidata":"https://www.wikidata.org/wiki/Q5142710"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/chester-county/colebrook-manor-84003239/"}
