The Old Idaho Penitentiary opened its doors in 1872 to some of the West’s most desperate criminals. Today, visitors can experience over 100 years of Idaho’s unique prison history with a visit to Solitary Confinement, cell blocks, and the Gallows. The site features thirty historic buildings and special exhibits including the J. Curtis Earl Memorial Exhibit, a collection of historic weaponry. Events and programs provide families, school groups, and visitors an opportunity to relive the Old Pen’s exciting past of daring escapes, scandals and executions.
