Eastern State Penitentiary was a notorious prison located in Philadelphia, Pennsylvania, USA. It was operational from 1829 to 1971 and was one of the most famous and expensive prisons in the world during its time. The prison was designed to be a radical departure from traditional prison design, incorporating principles of the Quaker belief in rehabilitation and penitence.

Eastern State Penitentiary's design was considered ahead of its time, as it was one of the first prisons to be built with individual cells, each equipped with running water and a flush toilet. The cells were also designed to allow minimal interaction between prisoners, with a focus on solitude and reflection.

Throughout its history, Eastern State Penitentiary housed some of the most notorious criminals of the time, including Al Capone and Willie Sutton. Despite its reputation as a model of progressive prison design, the conditions in Eastern State were often brutal and inhumane, with reports of severe overcrowding, harsh punishments, and inadequate healthcare.

Today, Eastern State Penitentiary is a National Historic Landmark and a museum, offering tours and exhibits that provide a unique insight into the history of American corrections. The museum offers a range of interactive exhibits, audio tours, and historical artifacts, providing visitors with a vivid sense of what life was like inside the prison.

Visitors can also explore the prison's restored cellblocks, solitary confinement cells, and other areas, giving them a glimpse into the history of this notorious prison. The museum also provides a range of educational programs, including school tours and workshops, aimed at increasing public understanding of the history of American corrections.
