Built in 1829, Eastern State Penitentiary was once the most famous and expensive prison in the world. The building opened as a museum in 1994, a haunting world of crumbling cellblocks, empty guard towers, and audio-tour-traveling visitors. For more than a decade, the prison has had an active contemporary art program. The organization's preservation, interpretation, and public programs prompt visitors to engage in dialogue and deepen a national conversation about criminal justice.
