It also forms part of a notable corner with two nearby religious buildings.","narrative":"Cincinnati City Hall occupies an entire block at 801 Plum Street, bounded by Eighth, Plum, Ninth and Central. Ground was broken in 1888 and the building was dedicated on May 15, 1893. Samuel Hannaford & Sons designed it in the Richardsonian Romanesque style, and David Hummel handled the brick and stonework. The rusticated granite and sandstone walls carry carved foliated panels, paired colonnettes, arcaded windows and a tile roof topped with metal finials, while a nine-story clock tower marks the southeast corner. Inside, marble stairs rise beneath stained glass windows showing allegorical scenes of early Cincinnati. Dedication-day accounts called it the most magnificent city hall in the country. After the Chamber of Commerce Building by H. H. Richardson was lost in 1911, it became the city's best surviving example of Romanesque Revival design. Together with the neighboring Isaac M. Wise Temple and St. Peter-in-Chains Cathedral, it anchors a notable corner of the city.","period_of_significance":"19th Century (completed 1893)","architect_builder":"Samuel Hannaford & Sons, architects; David Hummel, brick and stonework contractor","architectural_style":"Richardsonian Romanesque","criteria":[],"status_note":"Condition listed as excellent and unaltered, on its original site, in use as a city government building.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:53:09.889964-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_OH/72001017.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/72001017/86ecb3c887-800.webp","url_1600":"https://nationalhistoricalregister.com/media/72001017/86ecb3c887-1600.webp","licence":"CC BY-SA 3.0","author":"Greg Hume (talk)","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:CincinnatiCityHall.jpg\" rel=\"noopener\">Greg Hume (talk)</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:CincinnatiCityHall.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71985340","wikipedia":"https://en.wikipedia.org/wiki/Cincinnati_City_Hall","wikidata":"https://www.wikidata.org/wiki/Q5120236"},"indexable":true,"url":"https://nationalhistoricalregister.com/ohio/hamilton-county/cincinnati-city-hall-72001017/"}
