The construction date and builder are unknown, though it is thought to date from about the same time as two other round barns in the same group.","why_significant":"The barn is considered a noteworthy design variation among the round barns in its group. Its specially braced roof and squat cupola resemble the Fehr barn, but it differs in having no silo. Its characteristics suggest it was built by the Shaffer-Haas team around the same time as the Fehr and Bruce barns.","narrative":"Near Eleroy in Stephenson County, Illinois, this round barn measures 55 feet across and rests on a poured concrete foundation. It has a west entrance at ground level, while the animal entrance in the southeast quadrant has been permanently closed with a gate. Asphalt-covered drop siding encloses the walls, and a single-hip roof with asphalt shingles is capped by a squat cupola. Diagonal members between the loft studs brace it against wind, and each rafter is braced by a member nailed near the roof hip. The barn is the most altered in its group: steel I-beams on steel jacks have replaced the two concentric loft plates, and it is now used for storage. It remains in good condition apart from needed roofing. Its specially braced roof and cupola resemble the Fehr barn, but it has no silo. Its features suggest it was built by the Shaffer-Haas team at about the same time as the Fehr and Bruce barns, though the date and builder are unknown.","period_of_significance":null,"architect_builder":"Unknown; possibly the Shaffer-Haas team","architectural_style":"Round barn","criteria":[],"status_note":"Now used for storage; in good condition except for needed roofing.
