Bell, a prominent local inventor and manufacturer, and describes it as architecturally significant. Its Chateauesque design, Eastlake porch detailing and original interior woodwork and staircase are noted.","narrative":"Set back from the street on a large lot shaded by tall old trees, this brick mansion at 225 Oak Street in Hillsboro was completed in 1883 to designs by Cincinnati architect Henry Bevis. It is a three-story Chateauesque house laid in common bond, with a steeply pitched hipped roof topped by metal cresting, gabled dormers and three corbelled chimneys. Small wooden porches and covered balconies carry Eastlake-style posts, spindles and pendants. A stone dateplate reading 1883 sits above the first-floor windows of the projecting front bay, and the entrance has double wooden doors beneath a stained glass transom. Inside, original woodwork, wainscoting and hardwood floors survive, along with a carved walnut staircase that rises three stories beneath a skylight of colored glass. The house was listed as part of a group of buildings linked to C.S. Bell, a prominent local inventor and manufacturer, and was judged architecturally significant as well. Its roof was recently re-covered, but the original slate color pattern was kept.","period_of_significance":null,"architect_builder":"Henry Bevis, Cincinnati","architectural_style":"Chateauesque","criteria":[],"status_note":"Described as in good to excellent condition, altered but on its original site; the original slate roof was recently replaced with composition shingles that keep the original color pattern.","vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:53:12.362574-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_OH/80003099.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/80003099/b9178d15ef-800.webp","url_1600":"https://nationalhistoricalregister.com/media/80003099/b9178d15ef-1600.webp","licence":"CC BY-SA 3.0","author":"Aesopposea","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:CSBellMansion.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:CSBellMansion.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71985494","wikipedia":null,"wikidata":"https://www.wikidata.org/wiki/Q138360297"},"indexable":true,"url":"https://nationalhistoricalregister.com/ohio/highland-county/bell-mansion-80003099/"}
