The house, barn and outbuildings together show what the early rural built environment looked like, a grouping now rarely found in the county. It has stayed in the Trop family since 1811 and is described as the second oldest continuously family-owned farm in the county.","narrative":"Four miles west of Hillsboro in Highland County, Ohio, this small farmstead preserves a complete group of nineteenth-century farm buildings. The main house is a two-story, five-bay brick I-house laid in common bond, with a rear wing, limestone foundation, standing seam tin roof and plain walnut woodwork. The former kitchen, now the dining room, keeps its large cooking fireplace, wide oak floor and narrow corner stairway. The barn, dated to about 1815, rests on two original log pens with half-dovetail corners, later enclosed by additions and siding. Outbuildings include a buggy shed and corncrib, smokehouse, privy, henhouses, butchering shed, washhouse and a ca. 1930 milkhouse. Henry Trop settled the land in 1811 after arriving from Pennsylvania, and he and his son Philip built the brick house in the late 1840s. Few such groupings survive in a county now marked by modern agricultural buildings. The land has remained in the Trop family since 1811.","period_of_significance":"1800-1899","architect_builder":"Builders: Henry and Philip Trop","architectural_style":"I-house (classical I-house with Federal fireplaces)","criteria":[],"status_note":"Occupied and in use as agriculture and a private residence; condition marked good, unaltered, original site.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:53:12.81139-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_OH/82003597.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/82003597/18d6be774d-800.webp","url_1600":"https://nationalhistoricalregister.com/media/82003597/18d6be774d-1600.webp","licence":"CC BY-SA 3.0","author":"Aesopposea","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:TropFarm.JPG\" rel=\"noopener\">Aesopposea</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:TropFarm.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71989349","wikipedia":null,"wikidata":"https://www.wikidata.org/wiki/Q138362101"},"indexable":true,"url":"https://nationalhistoricalregister.com/ohio/highland-county/trop-farm-82003597/"}
