The prison opened in 1829, the first prison in the country built specifically with the intention of reforming rather than simply punishing criminals. The prison's hub-and-spoke layout was also a first, and became the model for hundreds of prisons around the world (it was often called the "Pennsylvania Model"). Its unique system of solitary confinement for all prisoners did not, however. Intended to provide prisoners relief from the overcrowding and squalor of other prisons and give them time to reflect on their crimes, it led instead to intense despair and sometimes insanity among the inmates and was roundly condemned by Dickens when he visited.
