The Old Idaho State Penitentiary
Opened in 1872, the Old Idaho Penitentiary was a functioning prison for over a 100 years. The “Ol Pen” housed some of the hardest criminals in the West, who were often subjected to harsh treatment. Now a museum, a walk through the complex allows visitors to see artifacts of the prison and learn about the living conditions of the the inmates and guards who lived here.
