Wyoming Prison State Historic Site

See this historic 1872 federal prison.

One of the oldest buildings in Wyoming is the Wyoming Territorial Prison. This former federal government prison located near Laramie, Wyoming, operated as a federal penitentiary from 1872 to 1890 and as a state prison from 1890 to 1901. During this time, 1,063 malicious convicts came through the iron doors and stayed in these cells because of their crimes. The prison became a symbol of law and order during the turmoil of the wild west. Butch Cassidy was one of the infamous inmates at this prison.

The exhibits at the historic prison now serve as a museum telling the story of Wyoming's past. You will hear the stories of infamous outlaws that passed through this prison for 30 years. Visitors also learn of the punishment and rehabilitation of the prisoners and can tour some furnished cells and listen to stories. The tour also includes the dining area, the guard's quarters, the infirmary, the women's quarters, the laundry room, and the warden's office. Guided and self-guided tours are available for guests.

The prison had a broom factory called The Prison Industries Building that was used to raise funds. It was also a rehabilitative strategy for the prison population as they worked in the factory. This old factory is set up for visitors to view and see how it worked. The prison museum sits on 197 acres featuring restored historic buildings, exhibits, a picnic area, and a nature trail. There is also a visitors center with a gift shop and an RV dump station for guests that have that need.
