The Miller Round Barn was a historic building located near Sharon Center in rural Johnson County, Iowa, United States. It was constructed in 1918 by John Schrader. The bank barn that was built on a slope was an example of the Illinois Agricultural Experiment Station / H.E. Crouch type.[1] The building was a true round barn that measured 60feet in diameter.[2] It was covered in white vertical siding and features a two-pitch roof and a 10feet central silo.[2] It was listed on the National Register of Historic Places since 1986. The barn has subsequently been torn down.[2]
