Since 1868, the Lansing Correctional Facility (formerly the Kansas State Penitentiary) has stood watch over what would become the city of Lansing. Designed by Erasmus Carr, architect of the Kansas State Capitol, the prison is the oldest in Kansas. In the beginning, it housed male and female inmates from Kansas and Oklahoma, as well as inmates serving federal sentences. Today, the facility's population of minimum, medium, maximum, and special management custody offenders is approximately 2,400. Leavenworth County has also seen the addition of the United States Disciplinary Barracks, United States Penitentiary-Leavenworth, and Corrections Corporation of America-Leavenworth, making it the only county in the country to host a state, military, federal, and private prison. Images of America: Lansing Correctional Facility features photographs of the early days, when inmates were on the "silent system" and could not speak to one another, to more modern times when rehabilitation has become an important component of prison life.
