Brandywine is the 18th-century house where Rebecca Lukens lived and managed the Brandywine mill; Terracina is a Gothic Revival house built around 1850 for her daughter Isabella.","why_significant":"The district is argued to be significant for Rebecca Lukens's leading role in the 19th-century American iron industry as manager and owner of the Brandywine Ironworks, later Lukens Steel Company, and as the only woman in the antebellum period to head a heavy industry with interstate and international interests. The grouped houses and office building are presented as tangible illustrations of the family's progression of success and management in the company.","narrative":"Four buildings on one block of South First Avenue in Coatesville make up this district, centered on the Lukens family and the Brandywine mill. Brandywine, the house Rebecca Lukens lived in from 1816 until her death in 1854, has 18th-century stone and stucco sections and sits beside the rolling mill she managed. Terracina, a Gothic Revival house around 1850, was given by Lukens to her daughter Isabella on her marriage to Dr. Charles Huston. Graystone, commissioned in 1889 by grandson Abram Francis Huston, was designed by Cope and Stewardson, as was the 1902 main office building. The district is significant for Rebecca Lukens's management of the iron works after her husband's death in 1825, at a time when few women headed heavy industry. Her firm supplied boiler plate to markets across the United States and to England, and the houses show the growing prosperity of the company and family over the following decades.","period_of_significance":"1825-1930","architect_builder":null,"architectural_style":"Brandywine: No Style; Terracina: Late Victorian Gothic; Graystone/Lukens Main Office Building: Late 19th- and 20th-century Revivals, Late Gothic Revival and Colonial Revival","criteria":["B"],"status_note":"Both the company store attached to Brandywine and Brandywine itself are currently vacant.","vacant_flag":true,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:29.998513-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/94001186_NHL.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/94001186/382d7ce6a5-800.webp","url_1600":"https://nationalhistoricalregister.com/media/94001186/382d7ce6a5-1600.webp","licence":"CC BY-SA 3.0","author":"Smallbones","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Terracina_from_NW.JPG\" rel=\"noopener\">Smallbones</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:Terracina_from_NW.JPG"},"district":{"nrhp_refnum":"87000667","name":"Coatesville Historic District","url":"https://nationalhistoricalregister.com/districts/pennsylvania/coatesville-historic-district-87000667/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71994169","wikipedia":"https://en.wikipedia.org/wiki/Lukens_Historic_District","wikidata":"https://www.wikidata.org/wiki/Q6702513"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/chester-county/lukens-historic-district-94001186/"}
