The Octagon Round Barn, Indian Creek Township is a historic building located near Iowa Center in rural Story County, Iowa, United States. It was built in around 1880 as a dairy barn.[1] The octagon-shaped building measures 50feet in diameter.[2] The modified hip roof, heavy timber framing, rectangular interior plan, and general purpose use marks this as a design influenced by Lorenzo S. Coffin, who built the first round barn in Iowa.[1] It has been listed on the National Register of Historic Places since 1986. The barn has deteriorated significantly and it is essentially a pile of wood now.[2]
