Pete French Round Barn State Heritage Site
🏆🏆🏆🏆🏆 Cattle Baron’s Round Barn — Perfectly preserved 1880s round barn built by Oregon’s most powerful cattle baron
Pete French Round Barn State Heritage Site preserves one of the most remarkable agricultural structures in the American West — a perfectly circular, 100-foot-diameter stone barn built in the 1880s by Pete French, who controlled the largest cattle empire in Oregon’s history. French’s P Ranch ran over 100,000 head of cattle across 200,000 acres of the Harney Basin. The barn was used for breaking horses during winter — the circular design eliminated corners where a horse could trap a rider. French was shot and killed in 1897 in a dispute with homesteaders, ending an era of open-range cattle kingdoms.
