🏆 Official Guide: Pete French Round Barn State Heritage Site — The last surviving 1880s round barn from Peter French’s legendary Oregon cattle empire — a National Register of Historic Places landmark in the high desert of Harney County.
The Pete French Round Barn stands as a monument to the vast cattle operations that once dominated southeastern Oregon’s high desert. Built in the early 1880s by the French-Glenn Livestock Company, it is the last remaining round barn of two or three originally constructed by “Cattle King” Peter French — one of the most powerful ranchers in the 19th-century American West.

Peter French’s Cattle Empire
Peter French arrived in the Harney Basin in 1872 and built one of the largest cattle operations in the American West, controlling over 130,000 acres of rangeland. His French-Glenn Livestock Company ran thousands of cattle across southeastern Oregon’s vast high desert. French was murdered by a homesteader in 1897 in a dispute over land and water rights — a violent end that symbolized the closing of the open-range era.
