Its Federal-style form and ornament, built in the 1840s when Chillicothe builders had already embraced Greek Revival, support the idea that popular styles reach rural areas slowly after appearing in urban centers.","narrative":"Built around 1840 for Henry Mace, this two-story Flemish-bond brick I-house sits on State Route 104 roughly three miles north of Chillicothe in Ross County, Ohio. It has a two-story rear wing, a standing-seam metal roof, a stone foundation and watercourse, stone window headers and sills, and a recessed entry with reeded pilasters. A small brick springhouse behind the house is believed to date from the same period. The Mace family farmed the land, bought in 1818, until 1993. The house is significant for what it shows about how building styles spread. Although Chillicothe builders had adopted Greek Revival by the 1830s, the Mace house followed the older Federal vocabulary, suggesting that new architectural ideas moved slowly from city to countryside. After years of neglect, later owners rehabilitated the house for use as a bed and breakfast while keeping its original form, room arrangement and most exterior materials.","period_of_significance":"ca. 1840","architect_builder":"Unknown","architectural_style":"Federal","criteria":["C"],"status_note":"Listed as vacant/not in use in the form's current function entry, although the narrative describes the house being rehabilitated as a bed and breakfast after about 8 years in derelict condition.","vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:52:07.625887-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_OH/98000101.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/98000101/3b68333b73-800.webp","url_1600":"https://nationalhistoricalregister.com/media/98000101/3b68333b73-1600.webp","licence":"CC BY-SA 3.0","author":"Aesopposea","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:HenryMaceHouse.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:HenryMaceHouse.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71991193","wikipedia":null,"wikidata":"https://www.wikidata.org/wiki/Q138667151"},"indexable":true,"url":"https://nationalhistoricalregister.com/ohio/ross-county/mace-henry-house-98000101/"}
