Council Bluffs is the location of the Pottawattamie County "Squirrel Cage" Jail, in use from 1885 until 1969, which is one of three remaining examples of a Rotary Jail. Listed on the National Register of Historic Places, it was built as a rotary jail with pie-shaped cells on a turntable. To access individual cells, the jailer turned a crank to rotate the cylinder until the desired cell lined up with a fixed opening on each floor. According to the Historical Society of Pottawattamie County, the Squirrel Cage Jail is the only three-story rotary jail constructed. Although the rotary mechanism was disabled in 1960, the building remained the county jail for another 9 years. Similar, smaller examples of the concept can be seen in Crawfordsville, Indiana and Gallatin, Missouri.
