Wyoming Frontier Prison
Rawlins, WY
Construction of the Wyoming Frontier Prison began in 1888 and completed in December 1901, opening with 104 cells, no electricity, no running water, and minimal heating. Over its operational history, 13,500 people were incarcerated there and 14 death sentences were carried out — nine by hanging and five in the gas chamber added in 1936. The prison closed in 1981 when a new facility opened near Rawlins.
