The farm includes a stone spring house, a frame wash house and a large frame bank barn.","why_significant":"The nomination argues the house is an unusually refined dwelling for a Pennsylvania farmhouse, with Federal style woodwork and fireplace treatments, and precision chiseled masonry on the principal facade. It also describes an unusual combination of hipped and gable roofs on an L-shaped plan. Secondary significance is tied to the farm's association with milling, agriculture and commerce, including a straw board mill.","narrative":"Built of native limestone in the first quarter of the 19th century, most probably between 1810 and 1825, this two-story farmhouse near Chambersburg is a rare example of refined Federal style design in a rural Pennsylvania setting. Its front facade has finely chiseled stone set with narrow mortar joints, while the side and rear walls use hammer-faced coursed stone. The entrance has an elaborate semi-circular fanlight, and the house holds eight fireplaces, each with a different mantel. Its mixed hipped and gable roof on an L-shaped plan is uncommon among southern Pennsylvania farmhouses. The property is also tied to local milling and farming, including a straw board mill that was sold separately in the late 19th century. A stone spring house, a frame wash house and a late 19th-century bank barn stand on the 7.86-acre tract.","period_of_significance":"c. 1820","architect_builder":null,"architectural_style":"Federal; Greek Revival front porch","criteria":["C"],"status_note":"The buildings are described as being in excellent condition.","vacant_flag":false,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:29.755184-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/79002227.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/79002227/d58eca118d-800.webp","url_1600":"https://nationalhistoricalregister.com/media/79002227/d58eca118d-1600.webp","licence":"CC0","author":"Smallbones","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Brotherton_Farm_FrankCo_Springhouse.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:Brotherton_Farm_FrankCo_Springhouse.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71994989","wikipedia":"https://en.wikipedia.org/wiki/Brotherton_Farm","wikidata":"https://www.wikidata.org/wiki/Q4975733"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/franklin-county/brotherton-farm-79002227/"}
