It is also the only survivor of three round barns Carmack built within a two-mile radius.

Built in 1915 by local carpenter Dick Carmack for George Welch, it rests on a poured concrete foundation and is covered in horizontal wooden siding beneath a single-hip roof of wooden shingles. A metal ventilator rises 40 feet above grade. The main entrance faces west, with secondary entrances on the south and northwest. A central wooden silo requires a semi-circular driveway between the entrances, and the haymow begins at roof level and runs three-quarters of the way around the interior. The barn is reported to be in excellent condition, with all of its original materials and no alterations. It was listed as a representative Illinois example of a building type. It is also the lone survivor of three round barns that Carmack built within a two-mile radius, which adds to its local importance. The nominated area is a circle 90 feet across, centered on the barn.","period_of_significance":null,"architect_builder":"Dick Carmack","architectural_style":"Round Barn","criteria":[],"status_note":"Described as in excellent condition, with all original building materials and no alterations.","vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:55:35.519533-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/67/8913/28891367/content/electronic-records/rg-079/NPS_IL/82002586.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/82002586/ebab1b9230-800.webp","url_1600":"https://nationalhistoricalregister.com/media/82002586/ebab1b9230-1600.webp","licence":"CC BY-SA 4.0","author":"Jon Roanhaus","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Clarence_Kleinkopf_Round_Barn_NRHP_82002586_McDonough_County,_IL.jpg\" rel=\"noopener\">Jon Roanhaus</a>, <a href=\"https://creativecommons.org/licenses/by-sa/4.0\" rel=\"license noopener\">CC BY-SA 4.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Clarence_Kleinkopf_Round_Barn_NRHP_82002586_McDonough_County,_IL.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/28891367","wikipedia":"https://en.wikipedia.org/wiki/Clarence_Kleinkopf_Round_Barn","wikidata":"https://www.wikidata.org/wiki/Q5126628"},"indexable":true,"url":"https://nationalhistoricalregister.com/illinois/mcdonough-county/kleinkopf-clarence-round-barn-82002586/"}
