Situated in Philadelphia, Eastern State Penitentiary, commonly known as ESP, stands as the United States' inaugural large-scale correctional facility. Although the nation had previously constructed various jails, none matched the monumental scale of ESP, which Pennsylvania established in the late 18th century. This institution laid the groundwork for the modern mega-prisons that now populate the U.S. landscape.
The grim experiences of inmates at Eastern State have influenced incarceration practices nationwide for centuries. Originating as Philadelphia’s Walnut Street Jail in 1776, the facility expanded by 1790 with the addition of a “Penitentiary House.” The cells were minuscule, some as small as 6 x 8 feet (1.8 x 2.4 meters), designed to isolate prisoners in solitary confinement for extended periods. As Philadelphia burgeoned post-independence, the jail grew, culminating in its final incarnation as Eastern State Penitentiary by 1821.
This colossal prison, located in the heart of Philadelphia, housed a wide array of violent and dangerous criminals. Emphasizing solitary confinement, many cells were reduced to a mere 4 feet (1.2 meters) wide. Inmates were crammed into these tight spaces, enduring years of isolation. The psychological strain led to frequent suicides and violent outbursts, leaving an immeasurable mental health impact on those imprisoned.
Despite its harsh conditions, the mega-prison gained favor among city officials seeking to detain the most severe offenders. Its design was replicated in states from Massachusetts to Tennessee, becoming the standard for all subsequent mega-prisons in America. Although ESP closed fifty years ago, its legacy continues to loom over Philadelphia. Join us as we explore ten astonishing facts about the creation, evolution, and eventual closure of America’s first penitentiary.
10. A Grand Vision for Walnut Street Jail
In 1821, Philadelphia and Pennsylvania invested $100,000 to expand the Walnut Street Jail, a staggering sum for the era. The city aimed to ensure the prison’s effectiveness to justify the expenditure. The original jail was small, overcrowded, and inefficient, but the new Eastern State Penitentiary promised to revolutionize the concept of incarceration.
The philosophy behind large-scale solitary confinement was largely influenced by Thomas Bradford, a former inspector at Walnut Street Jail and a member of what would become the Philadelphia Prison Society. Bradford believed the jail’s management of inmates was inadequate and advocated for isolating prisoners. Unaware of the psychological dangers of solitary confinement, Bradford and his contemporaries focused on rehabilitating some inmates while isolating others deemed beyond reform.
Bradford and his supporters viewed Walnut Street and similar jails as failures prior to ESP’s development. Proponents of solitary confinement at the new mega-prison emphasized two additional pillars: religious guidance and vocational training. These elements, combined with isolation, formed the “Pennsylvania system” of inmate rehabilitation. As ESP was constructed, Bradford ensured the facility aligned with these three objectives.
Prison authorities believed the mega-prison’s environment would foster remorse among its inmates. Solitary confinement was intended to encourage reflection on past wrongs, while religious instruction offered a path to spiritual renewal. Vocational training in trades such as carpentry and blacksmithing aimed to equip prisoners with practical skills for reintegration into society.
9. No Cost Was Too Great
Throughout the 1820s, laborers worked tirelessly to renovate and expand the Walnut Street Jail. By 1829, the upgraded facility was nearly ready to begin operations. ESP featured a groundbreaking radial design, resembling the spokes of a bicycle wheel, with seven cell blocks containing 76 cells each. To enforce total isolation, the cells were separated by stone walls 18 inches (45.7 centimeters) thick, preventing any communication between inmates.
The intention was for prisoners to spend almost their entire day confined to their cells. As a result, each small cell was equipped with a toilet and sink, though hygiene facilities were minimal. Although ESP started accepting inmates in 1829, it wasn’t fully completed until 1836. The final construction cost reached $780,000, equivalent to nearly $25 million today, making it one of the most expensive structures in the nation at the time.
In late 1829, Eastern State Penitentiary admitted its first inmate, Charles Williams, an 18-year-old Black farmer. Williams was sentenced to two years of solitary confinement for stealing a gold key and a silver watch, valued at approximately $25 (around $800 today). His case marked the beginning of ESP’s era of strict incarceration.
Philadelphia officials were determined to enforce harsh penalties, and the public supported stringent justice. Williams and others like him were meant to serve as warnings. Upon arrival, Williams was treated as a dangerous criminal, with guards covering his head to prevent him from memorizing the prison’s layout. Over the years, thousands more followed Williams into ESP, many convicted of far more serious offenses than petty theft.
8. Existence in Isolation
Upon completion, most cells at ESP measured 12 x 8 feet (3.7 x 2.4 meters). Inmates spent an average of 23 hours daily confined to these cramped spaces, with only an hour allocated for exercise—contingent on good behavior. Religious services were provided, and officials like Bradford from the Philadelphia Prison Society believed the prison’s design would “inspire and facilitate reform in the prisoners’ minds.”
Inmates, isolated nearly 99% of the day, were expected to reflect on their crimes and commit to future improvement. Despite their confinement, they were kept occupied with manual labor, crafting items like chairs, textiles, or shoes. These products were sold in Philadelphia, with the proceeds covering prison maintenance, inmate meals, and other expenses.
Remarkably, inmates were often denied access to reading or writing materials. Wardens aimed to prevent communication with the outside world and limit intellectual engagement beyond prescribed religious teachings. Family visits were also prohibited, intensifying the psychological toll of isolation.
Even during mandatory religious services, inmates faced extreme restrictions. They were seated far apart, hooded, and separated by partitions to prevent interaction. This ensured prisoners remained unaware of their peers, as they rarely saw or heard from others within the facility.
7. Tormented Inmates and Broken Spirits
Spending 23 hours a day in solitary confinement for years is a form of psychological torture. However, in the early 19th century, prison authorities viewed it as a method to reform unruly individuals and cleanse them of their sins. When inmates at ESP caused disturbances, guards resorted to even harsher measures, including an early form of waterboarding.
Troublesome prisoners were shackled to walls or chairs, and guards would douse them with freezing water from a fire hose, shocking their systems. For continued misbehavior, inmates were subjected to an iron gag—a metal ring tightened around their necks, connected to chains on their arms. Any movement caused self-strangulation. In other instances, guards exposed naked prisoners to scorching steam in confined spaces.
These brutal punishments sometimes resulted in fatalities. By 1834, ESP Warden Samuel R. Wood and his officers faced accusations of torturing inmates and embezzling prison funds. Despite these allegations, an internal committee cleared them of all charges, allowing the abuses to continue unchecked.
Torture and corruption persisted as accepted practices. By the early 20th century, ESP guards had refined their methods of solitary confinement. Problematic inmates were moved to even smaller cells, measuring just 4 x 8 feet (1.2 x 2.4 meters), where prolonged isolation drove many to madness. For over a century, these inhumane practices endured, with no improvement in morale or conditions.
6. Notorious Prisoners of ESP
Like many American penitentiaries, ESP housed its share of infamous criminals during its nearly 150 years of operation. Among the thousands of inmates was William Francis Sutton, a bank robber better known as Slick Willie. His notoriety made him one of the prison’s most recognizable figures.
In 1934, Sutton was sentenced to 25 to 50 years at ESP for a string of armed robberies. Over the next decade, he became a disruptive force within the prison, constantly seeking ways to escape. Eleven years into his sentence, Sutton lived up to his nickname by breaking out with a group of inmates. Although the FBI quickly recaptured him, his escape earned him a life sentence, which he served at Philadelphia County Prison due to his familiarity with ESP.
ESP also held other high-profile criminals, including the infamous Chicago gangster Al Capone. Known as Scarface, Capone was imprisoned at ESP on bootlegging charges, marking his first incarceration. However, his stay was brief, lasting less than a year before his release.
Another notable inmate was Leo Callahan, who achieved fame for his daring escape in 1923. Along with five others, Callahan fled the prison, but while his accomplices were quickly apprehended, he vanished without a trace. His successful escape remains unmatched in ESP’s history.
5. Overcrowding Leads to Suffering
When ESP became fully operational in 1835, it housed around 250 inmates. However, by the late 19th century, the population had surged to over 1,000, far exceeding the prison’s capacity. This overcrowding led to shockingly high mortality rates within its walls.
In the first two decades of ESP’s operation, approximately 10% of inmates died during their incarceration. Black inmates from Philadelphia’s most impoverished neighborhoods faced even harsher conditions, with up to 25% perishing during their sentences in the prison’s early years.
The overcrowding crisis worsened in the early 1900s, forcing ESP to house two inmates in cells originally designed for one. These cramped conditions, combined with poor sanitation, allowed diseases like tuberculosis to spread rapidly, turning an already dire situation into a deadly one.
To address the overcrowding, prison officials hastily constructed additional cells, many of which were underground and lacked windows or plumbing. Inmates dubbed these units “Klondike” due to their freezing conditions. Despite these efforts, the prison population continued to grow, and by 1913, ESP abandoned its solitary confinement policy, unable to manage the overwhelming number of inmates.
4. Inmates Rise Against Oppression
As conditions deteriorated, inmates began to resist. Organizing revolts was challenging, especially under solitary confinement, but overcrowding pushed prisoners to fight back. ESP witnessed at least three major uprisings and numerous smaller conflicts throughout its history.
The first significant rebellion occurred in the 1840s. Despite strict isolation, 11 Black inmates ingeniously communicated through the prison’s plumbing pipes to plan a mass escape. Several men, including former slaves, successfully fled before guards could intervene.
More violent uprisings erupted in the 20th century. In 1933, inmates revolted against guards accused of torture, nearly seizing control of a prison wing. Although reinforcements quashed the rebellion, the instigators faced brutal retaliation from the very guards they had accused.
The largest revolt took place a decade before ESP’s closure. On January 8, 1961, over 800 inmates clashed with guards and each other. Prepared guards swiftly suppressed the uprising, but the violence was so severe that officials later destroyed records documenting the event.
3. The Decline and Transformation of Eastern State
After enduring over a century of harsh conditions, inmates began to see improvements in the 1950s. Pennsylvania scrutinized the prison’s operations, renaming it “State Correctional Institution-Philadelphia” and adding a diagnostic center for mentally ill prisoners. While this was a step forward, it wasn’t sufficient to address the deep-rooted issues.
Conditions worsened in the 1960s, leading Pennsylvania to close the prison in 1971. The facility was sold to Philadelphia, sparking debates over its future use. Suggestions ranged from converting it into a city jail to developing it into a business park. As discussions dragged on, the site fell into ruin, with nature reclaiming the crumbling structure over two decades.
In 1991, Philadelphia finalized plans for the site, now a historical landmark. The city aimed to preserve its history and educate the public about incarceration. That fall, officials restored parts of the prison and began offering guided tours.
Initially, tours were seasonal, focusing on the prison’s eerie atmosphere during Halloween. Their popularity led to year-round operations, supported by private funding and grants. In 1994, a museum opened in one wing, showcasing artifacts and stories from ESP’s past. Today, thousands visit annually to explore its dark and compelling history.
2. From Suffering to Sightseeing
As previously noted, Eastern State Penitentiary permanently closed in 1971. Since then, it has transformed into a macabre yet captivating destination for both locals and tourists. Interestingly, its appeal as a tourist site began over a century earlier, drawing curious onlookers from across the mid-Atlantic even during its operational years.
Visitors to Philadelphia were drawn by tales of ESP’s harsh conditions and notorious inmates. The prison became a must-see attraction, rivaling other landmarks in the City of Brotherly Love by the mid-19th century.
Just as ESP housed infamous criminals, it also attracted notable visitors. Among them was Charles Dickens, the renowned English author of A Tale of Two Cities and Great Expectations. During his 1842 visit, Dickens marveled at the prison’s architecture but was appalled by the inhumane solitary confinement conditions.
Dickens later described the inmates’ plight, writing, “He sees the prison-officers, but with that exception, he never looks upon a human countenance, or hears a human voice. He is a man buried alive; to be dug out in the slow round of years; and in the meantime dead to everything but torturing anxieties and horrible despair.”
1. Even Dogs Weren’t Spared
Despite ESP’s grim reputation, inmates sought moments of levity. One such instance occurred in 1924 when a black Labrador named Pep was registered as inmate C-2559. Accused of killing the Pennsylvania governor’s wife’s cat, Pep was humorously sentenced to life in prison, though the dog was oblivious to the joke.
The governor’s playful order to incarcerate Pep provided ESP with much-needed positive publicity. The story quickly gained national attention, making Pep an unlikely celebrity long before the concept of “going viral” existed.
However, the public reaction was far from favorable. Thousands of Pennsylvanians criticized Governor Pinochet for punishing an innocent animal, with some complaints even arriving from overseas. The backlash grew over the next two years, as more people condemned Pep’s imprisonment.
In 1926, the governor addressed the controversy, clarifying that Pep’s “life sentence” was a joke and that the dog was well-treated. Despite the explanation, Pep remained in prison, eventually being transferred to another facility in 1928, where he lived out his days as a beloved figure among inmates.
