We are asking all visitors to please wear a mask inside the buildings.

Built in 1872 and restored in 1989, the prison is the highlight of the WTPSHS. Pick up a brochure in the gift shop and head toward the prison for a self-guided tour. (Development of an audio tour system is in the works.) Plan to spend at least an hour inside. Stops along the tour include: furnished cells, the prisoners’ dining area, guard’s quarters, infirmary, women’s quarters, laundry room, warden’s office, and various exhibit galleries. New exhibit’s include: Found During Restoration: Artifacts Uncovered (including items found during the History Channel sponsored, Unlocking Secrets in the Soil project), N. K. Boswell: Warden and Lawman, Innocent or Guilty? Women Inmates of the Wyoming Territorial Prison, and a new exhibit on Butch Cassidy.
