"The Eastern State Penitentiary is considered one of America's most historic former prisons. It was operational from 1829 until 1971 and is located on Fairmount Avenue between Corinthian Avenue and North 22nd Street in the Fairmount section of Philadelphia, Pennsylvania. Its revolutionary system of incarceration was the first to establish the policy of separate confinement, emphasizing principles of reform rather than punishment. Notorious criminals such as bank robber Willie Sutton and Al Capone were held inside its unique wagon wheel design. When the building was erected it was the largest and most expensive public structure ever constructed, quickly becoming a model for more than 300 prisons worldwide."
