Old Pen Tours are a popular Rawlins activity.
During its more than 80-year history as a corrections facility, approximately 13,500 inmates called the Wyoming State Penitentiary in Rawlins “home.”
Wyoming’s Frontier Prison, often referred to as the “Old Pen,” housed 11 women from when it opened in 1901 until 1909, at which point it became a facility primarily for men.
