Old Idaho Penitentiary

Old Idaho Penitentiary

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.

Guided Tours are available most days for an additional $2 fee. Due to unpredictable weather and staff availability, guided tour reservations are only available on-site at the Old Idaho Penitentiary front desk.
