The Outlaw Trail ended here. Explore this 1872 federal prison that held “evil doers of all classes and kinds.”
Crime and Confinement
Listed on the National Register of Historic Places, the Wyoming Territorial Prison is an imposing stone structure built in 1872 (restored in 1990). For thirty years it held the West’s most violent and desperate outlaws (including the notorious Butch Cassidy) during the dramatic time of Wyoming’s territorial days and early Statehood.
Now a museum visitors can walk into the strap iron cells where convicts were locked up, worked and lived. The prison now houses convict photographs and displays relating to their confinement. Visit the prison broom factory and watch living history demonstrations on broom making just as the convicts did in the 1890s. Visitors will receive a “convict identity” and follow in the footsteps of convicted outlaws on a self-guided or guided tour (offered Fri-Mon).
Convicts to Cows
Today, the site’s rich history not only focuses on crimes, convicts, and confinement but also the quest for agricultural knowledge using science. In 1903, the existing prison buildings were re-purposed for the University of Wyoming’s Experiment Station. Discover how for eighty-six years livestock and crop field research advanced farming and ranching practices in Wyoming. The “Science on the Range” exhibit delves into the various experiments conducted on the old prison grounds.
Located on 197 acres, the site offers restored historic buildings, museum exhibits, a nature trail, picnic area, and visitor center with gift shop that features Wyoming made products.
