The Doncaster Round Barn, also called "Bayers' Barn" and "the Round Barn at Twin Bridges" is a three-story, wood-framed round barn located about 1.5 miles (2.4 km) north of Twin Bridges, Montana. Built about 1882 by mining entrepreneur Noah Armstrong to house his race horses, and featuring a 20 feet (6.1 m)-wide indoor circular aisle that was used for exercising horses, it is a National Register of Historic Places property notable for its unique architecture and as the birthplace of the Thoroughbred racehorse, Spokane, winner of the 1889 Kentucky Derby.[2]
