Museum - WYOMING TERRITORIAL PRISON
About:
The Outlaw Trail ended here! No need to commit a crime to "do time" at the Territorial Prison. Built first as a Federal Prison (1872-1890), it later became Wyoming’s State Penitentiary (1890-1903). During the 30 years it was in operation, 1,200 prisoners, including the notorious Butch Cassidy, walked through the front iron doors and occupied the cells. Now a museum, visitors walk the halls where prisoners were locked up, worked and lived.
Listed on the National Register of Historic places, the Wyoming Territorial Prison is an imposing stone structure built in 1872 and restored in 1990.
Visitors usually take a self-guided tour of the prison grounds, but during the summer season a limited number of drop-in, guided tours are available. Visit the prison Broom Factory to learn about the history of the buliding and how prisoners made brooms.
After the prison closed, the Site spent most of its life as an experimental stock farm station for the University of Wyoming. Visit the historic horse barn to see the exhibit, "Science on the Range" and learn more.
