Harding and his wife in 1890, with a small campaign headquarters building to the rear.","why_significant":"The house was the home of Warren G. Harding, 29th President of the United States, during his years as newspaper editor, state senator, lieutenant governor and U.S. Senator. He conducted his 1920 presidential \"front porch\" campaign from it. It is preserved as a historic house museum.","narrative":"Warren G. Harding's Marion, Ohio, residence at 380 Mount Vernon Avenue is a two-and-one-half story clapboard house painted green, with a wide front porch and an Indiana limestone foundation. Harding and his future wife planned it and built it in 1890, a year before their marriage. Inside, oak woodwork, a parlor with parquet floors and stained glass windows, and four simple bedrooms reflect a comfortable middle-class household. Behind the house stands a small white clapboard building that served as campaign headquarters and now displays campaign posters, cartoons, speeches and other mementos. The couple lived here while Harding edited the Marion Star and rose from state senator to lieutenant governor and U.S. Senator. In 1920 he campaigned for the presidency from the front porch, greeting thousands of visitors on the lawn. He served as the 29th President from 1921 until his death in 1923. His widow bequeathed the property to be kept as a historic house museum.","period_of_significance":"1891-1923","architect_builder":null,"architectural_style":"Described as \"style-less\" by one biographer, with Victorian features such as stained glass, scalloped shingles and wooden curlicue trim","criteria":[],"status_note":"Occupied, in good condition, and used as a museum open to the public.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:53:09.796436-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_OH/66000618_NHL.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/66000618/faf72a71f3-800.webp","url_1600":"https://nationalhistoricalregister.com/media/66000618/faf72a71f3-1600.webp","licence":"Public domain","author":"Nyttend","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Warren_G._Harding_House.jpg\" rel=\"noopener\">Nyttend</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Warren_G._Harding_House.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71986523","wikipedia":"https://en.wikipedia.org/wiki/Harding_Home","wikidata":"https://www.wikidata.org/wiki/Q5656096"},"indexable":true,"url":"https://nationalhistoricalregister.com/ohio/marion-county/harding-warren-g-house-66000618/"}
