About Yuma Territorial Prison State Historic Park
Sitting on a bluff overlooking the Colorado River, three miles west of the confluence of the Colorado and the historic Gila River, stand the ruins of Arizona’s famous Territorial Prison, and a short distance west are the remaining buildings that served as a part of the Yuma Quartermaster's Depot.
In 1876, ground was broken, and some of the prisoners were pressed into service to build their cells. The first seven inmates moved into the facility on July 1, 1876. The Prison held a variety of law violators, including the legendary stagecoach robber Pearl Hart. The Prison continued in operation for 33 years when, due to overcrowding, all inmates were moved to a new facility in Florence, Arizona.
