Background

The Old Allen County Jail is a former jail in Iola, Kansas, United States. Built in the late 1860s, it operated as a detention facility for nearly a century before a replacement opened; today, it is the Old Jail Museum, operated by the Allen County Historical Society, and it has been designated a historic site.
