The Old Idaho Penitentiary opened its doors in 1872 to some of the West’s most desperate criminals. Today, visitors can experience more than 100 years of Idaho’s unique prison history with a visit to solitary confinement, cell blocks, and the gallows. The site features 30 historic buildings and special exhibits including the J. Curtis Earl Memorial Exhibit which displays a collection of historic weaponry.
