Once roaring mining town, claimed 3,000 people in 1880. Beware of open mine shafts. 1876-1909, this penitentiary housed many of Arizona's most dangerous criminals. Famed in literature, movies and television, the remains of the prison are now an Arizona State Park. The cells, main gate and guard tower serve as grim reminders of frontier justice.
Museum exhibits document the prison's past.
Open 8 a.m. to 5 p.m. every day except Christmas Day.
