It is 55 feet in diameter, with tile walls and a central silo, and sits on a poured concrete foundation.","why_significant":"It is the last round barn on which the Haas brothers are known to have worked, since they built its roof, which links it to the many round barns of the area. Its masonry walls, metal-framed openings and specially braced hip roof contrast with the other barns in the group nomination. The roof bracing reflects the methods promoted by the University of Illinois agricultural experiment station.","narrative":"Located east of Durand in Winnebago County, Illinois, this round barn was built in 1917. It measures 55 feet across and rests on a poured concrete foundation, with a central silo 24 feet in diameter. Both the barn and silo walls are made of brown, hollow, vitrified tile. A banked earthen ramp on the north side gives access to the loft, and animals enter from the west. Entrances and windows are framed in metal. A single-hip roof, covered in wooden shingles and topped by a small metal ventilator, is braced on both sides of each rafter in the manner promoted by the University of Illinois agricultural experiment station. Two sets of contractors worked on the building: an unknown mason laid the foundation and tile walls, and the Haas brothers built the roof. The barn is considered the last round barn the Haas brothers are known to have worked on. It also shows the shift from local carpentry habits toward standardized designs, and its original materials remain intact.","period_of_significance":null,"architect_builder":"Mason unknown; roof by Haas brothers","architectural_style":null,"criteria":[],"status_note":"The form states that the original design and materials are completely intact.","vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:55:35.575073-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/92/8914/28891492/content/electronic-records/rg-079/NPS_IL/84001172.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/84001172/d49cbeeba0-800.webp","url_1600":"https://nationalhistoricalregister.com/media/84001172/d49cbeeba0-1600.webp","licence":"CC BY 2.5","author":"IvoShandor","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Durand_Il_Weber_Round_Barn6.jpg\" rel=\"noopener\">IvoShandor</a>, <a href=\"https://creativecommons.org/licenses/by/2.5\" rel=\"license noopener\">CC BY 2.5</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Durand_Il_Weber_Round_Barn6.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/28891492","wikipedia":"https://en.wikipedia.org/wiki/Robert_Weber_Round_Barn","wikidata":"https://www.wikidata.org/wiki/Q7350920"},"indexable":true,"url":"https://nationalhistoricalregister.com/illinois/winnebago-county/weber-robert-round-barn-84001172/"}
