A round barn is a historic barn design that could be octagonal, polygonal, or circular in plan. Though round barns were not as popular as some other barn designs, their unique shape makes them noticeable. The years from 1880 to 1920 represent the height of round barn construction. Round barn construction in the United States can be divided into two overlapping eras. The first, the octagonal era, spanned from 1850 to 1900. The second, the true circular era, spanned from 1889 to 1936. The overlap meant that round barns of both types, polygonal and circular, were built during the latter part of the nineteenth century. Numerous round barns in the United States are listed on the National Register of Historic Places.
The three University of Illinois round barns played a special role in the promotion and popularity of the American round barn. They are located in Urbana Township, on the border of the U.S. city of Urbana, Illinois and on the campus of the University of Illinois Urbana-Champaign. The University of Illinois was home to one of the Agricultural Experiment Stations, located at U.S. universities, which were at the heart of the promotion of the round barn. At least one round barn in Illinois was built specifically after its owner viewed the barns at the university. Though originally an experiment the three barns helped to lead the way for round barn construction throughout the Midwest, particularly in Illinois. The barns were listed as contributing properties to the U of I Experimental Dairy Farm Historic District, which was listed on the U.S. National Register of Historic Places in 1994.
