It began as part of the curtain wall of the 1788 Campus Martius fort and is now enclosed within the Campus Martius Museum, a state memorial.","why_significant":"It is the oldest known dwelling in Ohio and a surviving part of Campus Martius, the fortified village of the Ohio Company of Associates in the first permanent settlement in the Northwest Territory. Rufus Putnam, a Revolutionary War officer and Ohio Company superintendent, lived there. The nomination ties it to military and 18th-century settlement history.","narrative":"This house in Marietta, Ohio, began as one of the dwellings forming the walls of Campus Martius, a fortified village built in 1788 by the Ohio Company of Associates above the Muskingum River. Rufus Putnam, a Revolutionary War officer and company superintendent, lived in the unit beside the southeast blockhouse. The original part measured 18 by 36 feet, with four rooms, a basement and an attic. After Putnam bought it in 1796, a matching four-room section was added to the north, the roof was rebuilt and the facade widened from three bays to five. Several families lived there in the late 19th century. The fort was abandoned after the 1795 Treaty of Greeneville, and its lots and buildings were sold. The Putnam family stayed on. The Campus Martius Museum, completed in 1931, encloses the house. It is described as the oldest known dwelling in Ohio, and restoration to its fort-era appearance was in progress when it was listed.","period_of_significance":"18th Century","architect_builder":null,"architectural_style":null,"criteria":[],"status_note":"Owned by the State of Ohio and used as a museum; a complete restoration to its Campus Martius appearance was underway at the time of nomination.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:53:10.159206-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_OH/70000524.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/70000524/77cf3bc081-800.webp","url_1600":"https://nationalhistoricalregister.com/media/70000524/77cf3bc081-1600.webp","licence":"Public domain","author":"Thomas Summers","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Rufus_Putnam_House_1903.png\" rel=\"noopener\">Thomas Summers</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Rufus_Putnam_House_1903.png"},"district":{"nrhp_refnum":"01000903","name":"Marietta Historic District (Boundary Increase)","url":"https://nationalhistoricalregister.com/districts/ohio/marietta-historic-district-boundary-increase-01000903/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71991925","wikipedia":"https://en.wikipedia.org/wiki/Rufus_Putnam_House","wikidata":"https://www.wikidata.org/wiki/Q7378091"},"indexable":true,"url":"https://nationalhistoricalregister.com/ohio/washington-county/putnam-rufus-house-70000524/"}
