Between 1876 and 1909, this penitentiary housed many of Arizona's most dangerous and notorious criminals. Famed in literature, movies and television, the remains of the prison are now Arizona's most visited State Historic Park. The cells, main gate and guard tower have endured as grim reminders of frontier justice.
Museum exhibits document the story of the prison.
Opened 8 a.m.-5 p.m., every day except Christmas.
