The most notorious tourist sight in town, Yuma Territorial Prison, now an Arizona state historic park, was built for the most part by the convicts who were incarcerated here from 1876 until 1909, when the prison outgrew its location. The hilly site on the Colorado River, chosen for security purposes, precluded further expansion.
Visitors gazing today at the tiny cells that held six inmates each, often in 115°F heat, are likely to be appalled, but the prison—dubbed
the Country Club of the Colorado by locals—was considered a model of enlightenment by turn-of-the-20th-century standards: in an era when beatings were common, the only punishments meted out here were solitary confinement and assignment to a dark cell. The complex housed a hospital as well as Yuma's only public library, where the 25¢ that visitors paid for a prison tour financed the acquisition of new books.
The 3,069 prisoners who served time at what was then the territory's only prison included men and women from 21 different countries. They came from all social classes and were sent up for everything from armed robbery and murder to polygamy. R.L. McDonald, incarcerated for forgery, had been the superintendent of the Phoenix public school system. Chosen as the prison bookkeeper, he absconded with $130 of the inmates' money when he was released.
The mess hall opened as a museum in 1940, and the entire prison complex was designated a state historic park in 1961.
