Wyoming Territorial Prison State Park

(Wyoming)

The Wyoming Territorial Prison is a former federal government prison near Laramie, Wyoming. Built in 1872, it is one of the oldest buildings in Wyoming. It operated as a federal penitentiary from 1872 to 1890, and as a state prison from 1890 to 1901. It was then transferred to the University of Wyoming and was used as an agricultural experiment station until 1989. In 1991, the facility was opened to the public, and in 2004, it was designated as Wyoming Territorial Prison State Historic Site.
