Brief History of the Wyoming Territorial Prison

The Wyoming Territorial Prison began humbly enough in 1872 with enough space for about 4 dozen prisoners. The prisoners, however, found themselves with a little more space after nearly a quarter of the prisoners had escaped within the first two years of the prison’s existence.

Eventually, the escapees were replaced with new prisoners, and by the late 1870s, the prison was actually overcrowded. The busyness wouldn’t last.

When the feds rolled in to inspect the prison in the 1880s, the prisoner population had dwindled to less than a dozen inmates. Instead of closing the prison, the feds expanded the prison with a second cellblock capable of housing another 150 inmates. A central kitchen, dining hall, and other improvements were also added.

The expanded Wyoming Territorial Prison saw only a little more than a decade of activity as it was transferred to state control and eventually closed in 1903.

The property was then given to the University of Wyoming for agricultural and livestock research until 1989. A couple years later, the prison was opened to tourists.

During its run as a territorial and later state prison, the facility housed both men and women convicted of almost everything up to murder. Those convicted of murder were housed and executed elsewhere. (Probably due to the relative ease of escape in the early days of the prison.)

Of those locked in cells here, perhaps none is more notorious than Butch Cassidy. The famed outlaw spent roughly 18 months at the prison for stealing horses in the late 1800s, his only prison stint. Cassidy formed his “Wild Bunch” gang of criminals shortly after his release.
