The Kinney Octagon Barn was a historic agricultural building located just north of Burr Oak, Iowa, United States. Lorenzo Coffin was a stock breeder and the farm editor of the Fort Dodge Messenger. He is thought to have built the first round barn in Iowa in 1867.[1] The modified hip roof and heavy timber construction of this barn, built in 1880, suggests that it was a Coffin-type octagon barn. It was added to the National Register of Historic Places on November 19, 1986. It has subsequently been torn down.
