William Oakland Round Barn

The William Oakland Round Barn is an historic building located near Blairsburg in rural Hamilton County, Iowa, United States. The true round barn measures 50 ft in diameter. It is constructed of clay tiles and features a conical roof, aerator, a small dormer on the west side and a larger one on the east side as well as a 16 ft central silo. William T. Oakland had this structure built in 1910 as a combination hog and sale barn. The ground floor was used for farrowing, while the sale ring was on the upper level. The 16 windows in roof provided light to the sales area. The barn has been listed on the National Register of Historic Places since 1986.
