It is believed to have been built in 1811 by Erastus Adkins, likely as a tavern.","why_significant":"The nomination calls it one of the largest and most structurally complex log buildings in Ohio, with all walls, including the breezeway and kitchen ell, raised together and intricately notched. It is described as the first two-story, double log pen built in the Northwest Territory. Its large size, early date and unusual design make it a unique Ohio log structure.","narrative":"Near St. Martin in Brown County, Ohio, this two-story log building sits at the corner of Ohio SR 251 and US 50. Measuring about 47 feet by 18.5 feet, it is built of oak, curly maple and other woods using steeple-notched corners. It is believed to have been built in 1811 by Erastus Adkins, on land that came from a 1787 military grant, and was apparently a tavern serving travelers to the nearby St. Martins chapel and convent. In the 1840s it was remodeled as a home, gaining new windows, sidelights and a transom, and later it returned to tavern use as Murray's Corner. A fire in the kitchen ell led to the loss of some rear log walls, which were replaced with frame construction. It is considered one of Ohio's largest and most complex log buildings, because every wall was raised at once and notched together, unlike typical double pen houses. It has been described as the first two-story double log pen in the Northwest Territory.","period_of_significance":"19th Century (specific date 1811)","architect_builder":"Erastus Adkins (believed builder)","architectural_style":"Log construction, steeple notch; double pen with enclosed breezeway","criteria":[],"status_note":"Condition listed as good and altered, on its original site; present use is storage and the property is marked unoccupied.","vacant_flag":true,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:53:09.772842-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_OH/75001328.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/75001328/4738171381-800.webp","url_1600":"https://nationalhistoricalregister.com/media/75001328/4738171381-1600.webp","licence":"CC BY-SA 3.0","author":"Aesopposea","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Thumann_Log_House_located_in_northern_Brown_County,_Ohio.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:Thumann_Log_House_located_in_northern_Brown_County,_Ohio.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71986855","wikipedia":null,"wikidata":"https://www.wikidata.org/wiki/Q137605218"},"indexable":true,"url":"https://nationalhistoricalregister.com/ohio/brown-county/thumann-log-house-75001328/"}
