The prison first housed incarcerated men in 1872 when it served the Idaho Territory. It became the Idaho State Penitentiary after Idaho’s statehood in 1890. Over 13,000 men and 217 women called the penitentiary home at one time or another, including Idahoans as young as ten and eleven years old. Today their stories are told through a wide variety of special exhibits and preserved cell house structures that allow guests to experience mid-century life in a territorial prison. It closed in 1973, and became a history museum on December 14, 1974.
