Its size and construction reflect the early prosperity of Chillicothe. The setting among large oak and black walnut trees and the original furnishings give a memorable glimpse of the past.","narrative":"Oak Hill is a two-story sandstone house on a hilltop southwest of Chillicothe, Ohio. George William Dun, a Scottish-born importer of textiles in Philadelphia, moved to the area with his family in 1838 and built it between 1838 and 1840. Family tradition holds that he designed it after houses he admired in Philadelphia. The walls are locally quarried cut sandstone blocks, and the symmetrical front has a central doorway with transom and sidelights. Four sandstone chimneys rise above the hip roof. Inside, a central hall runs front to back, ending in an open staircase that reaches the attic. The woodwork and wood mantels are original, and a Franklin stove made in Chillicothe remains in a bedroom. The house has stayed in the family, and the author Charles Allen Smart was among its owners. It was listed as an outstanding example of the area's early sandstone architecture, reflecting Chillicothe's early prosperity.","period_of_significance":"19th Century (1838-1840)","architect_builder":"George William Dun (family tradition says he designed it)","architectural_style":"American vernacular adaptation of the Adam style","criteria":[],"status_note":"Stated to be in excellent condition and used as a private residence; largely as built except for the kitchen, cornice railing and mechanical equipment.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:53:09.274966-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_OH/73001527.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/73001527/af0cbf7aef-800.webp","url_1600":"https://nationalhistoricalregister.com/media/73001527/af0cbf7aef-1600.webp","licence":"Public domain","author":"Nyttend","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Oak_Hill_in_North_Fork_Village.jpg\" rel=\"noopener\">Nyttend</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Oak_Hill_in_North_Fork_Village.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71991179","wikipedia":"https://en.wikipedia.org/wiki/Oak_Hill_(Chillicothe,_Ohio)","wikidata":"https://www.wikidata.org/wiki/Q7073551"},"indexable":true,"url":"https://nationalhistoricalregister.com/ohio/ross-county/oak-hill-73001527/"}
