W.J. Buck Polygonal Barn
The W.J. Buck Polygonal Barn was a historical structure located near Diagonal in rural Ringgold County, Iowa, United States. It was built in 1907 and has been listed on the National Register of Historic Places since 1986. The building measures around. The structure of the barn was basically a central octagon with a sectioned roof. Double pitch sheds surrounded the barn characterizing it as an encircling wing type. The central section was six-sided and the wing was nine-sided. The plan appears to be the same as the one for the Lloyd Z. Jones stock barn published in Wallaces' Farmer on January 16, 1903 and again on October 25, 1907 and June 17, 1910. It has subsequently been torn down.
