It is called an excellent example of its type, with a notable Greek Revival exterior. The significance area checked is architecture.","narrative":"Standing on High Street in Mount Vernon, the Knox County Courthouse is a two-story brick building on a stone foundation, measuring roughly seventy by forty feet. Built in 1855-1856, it follows the Greek Revival style. The south entrance has fluted Doric columns supporting a pediment, the cornice carries triglyphs and metopes, and a square tower about thirty feet high with four clock faces and a metal dome rises from the roof. Inside, the offices are small, and asphalt tile has replaced most original flooring, though some mosaic tile survives in the west doorway. It is the fourth courthouse in the county, which was formed in 1808 and named for General Henry Knox. After the third courthouse was damaged beyond repair by 1854, county commissioners sought bids. Architect Daniel Clark designed the replacement, and contractors John Jennings and David Auld built it for $36,336. It was listed as an excellent example of its type.","period_of_significance":"19th Century (built 1855-1856)","architect_builder":"Architect Daniel Clark; contractors John Jennings and David Auld","architectural_style":"Greek Revival","criteria":[],"status_note":"Condition listed as good and altered, on its original site; occupied and in government use, with the interior floor coverings partly replaced.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:53:10.132053-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_OH/73001484.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/73001484/23d900cfdb-800.webp","url_1600":"https://nationalhistoricalregister.com/media/73001484/23d900cfdb-1600.webp","licence":"CC BY 2.0","author":"Mark Spearman from Newark, Ohio, USA","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Knox_County,_Ohio_Courthouse_(14516804607).jpg\" rel=\"noopener\">Mark Spearman from Newark, Ohio, USA</a>, <a href=\"https://creativecommons.org/licenses/by/2.0\" rel=\"license noopener\">CC BY 2.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Knox_County,_Ohio_Courthouse_(14516804607).jpg"},"district":{"nrhp_refnum":"86003490","name":"East High Street Historic District","url":"https://nationalhistoricalregister.com/districts/ohio/east-high-street-historic-district-86003490/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71989503","wikipedia":"https://en.wikipedia.org/wiki/Knox_County_Courthouse_(Ohio)","wikidata":"https://www.wikidata.org/wiki/Q6423548"},"indexable":true,"url":"https://nationalhistoricalregister.com/ohio/knox-county/knox-county-courthouse-73001484/"}
