Built in 1870, the Old Idaho Penitentiary is one of only four territorial prisons open to the public today. During its 101 years of operation, the site saw escapes, scandals and the effects of Boise’s transition from the “wild west” to a mid-20th century capital city. Step inside the four walls of the prison yard and imagine a life of confinement as steel doors close behind you.
