The text notes the structure appears residential in character and may have been extensively altered, or may have functioned as a schoolhouse before being used as a dwelling.","narrative":"A Greek Revival building in Coatesville, Chester County, Pennsylvania, the Robert Steen House was listed for its architectural character as a representative example of its type. The surviving text describes a structure that is residential in appearance, though it may have served earlier as a schoolhouse before being converted to domestic use. Because the form as available is largely incomplete, its physical description, construction date, builder and period of significance cannot be fully confirmed from the text. The property's significance rests on the survival of Greek Revival design features in a building of this kind in the Coatesville area, a region where many vernacular buildings of the period have been altered or lost. The nomination treats the house as a link to the early development of the town and to the regional spread of the Greek Revival style in southeastern Pennsylvania.","period_of_significance":null,"architect_builder":null,"architectural_style":"Greek Revival","criteria":[],"status_note":null,"vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:13:21.997387-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/85001155.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/85001155/e69c742aef-800.webp","url_1600":"https://nationalhistoricalregister.com/media/85001155/e69c742aef-1600.webp","licence":"CC BY-SA 3.0","author":"Timothy Colgan","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Robert_Steen_House.jpg\" rel=\"noopener\">Timothy Colgan</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:Robert_Steen_House.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71992738","wikipedia":"https://en.wikipedia.org/wiki/Robert_Steen_House","wikidata":"https://www.wikidata.org/wiki/Q7350023"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/chester-county/steen-robert-house-85001155/"}
