50 – Devil’s Island

Located over 40 meters above sea level on a remote island off the coast of French Guiana, this prison was a dumping ground for those opposing Napoleon III’s coup d’état.

Filled with a variety of various deadly tropical diseases, thanks mainly to limited sanitary systems and a prolific mosquito infestation that wiped out much of the prison population.

France was a harsh place to receive a prison sentence in the late 19th century and those with more than eight years were doomed to remain on the island for the rest of their lives, mainly due to the extreme living conditions.

While Devil’s island was mainly reserved for hardened criminals such as murderers and thieves, some women were also deported to the island in an attempt to keep the population sustainable.

Incredibly, the island was still operating in 1938, however by 1953, it was closed and any remaining prisoners were returned to mainland France, with some even electing to remain on the island.

Visitors can still view the island from boats, however it is strictly off-limits to the public.


49 – Pelican Bay State Prison

Used to house some of the most difficult and dangerous prisoners in California, Pelican Bay opened in 1989 and earned its reputation for having a system that is used to break the psychological well-being of inmates.

One of the few supermax facility’s in the state, the prison sits on 275 acres of land in Del Norte County and is named after a shallow bay on the pacific coast.

The prison is split onto two areas, one being general population and the other being nicknamed the SHU, or special housing unit for short.

Surrounded by an electric fence, this is the most degrading part of the prison with inmates confined to their cells for 22 hours each day and only fed two meals.

No windows exist in cells and prisoners are forced to exercise in a concrete yard known as the dog run.

Many SHU prisoners often make it back into general population, however many of the 3,000 inmates who have served more than eight years in solitary say they still suffer from SHU syndrome.

Of the notable inmates in Pelican Bay, the most famous has to be Robert Walter Scully, a man sentenced to death for fatally shooting a Sonoma County sheriff’s deputy in 1995.


48 – McNeil Island

Famous for having a beautiful view of the ocean, unfortunately, any escapees will probably drown in an attempted escape, thanks to the deadly undercurrents of Pitt Passage.

One of America’s last remaining Island prison’s, its noted as being more dangerous for escaping inmates than those locked inside.

The strict rehabilitation regime became known as the “Auburn System” and the prison suffered many riots and scandals.

Inmates often sprayed acid in an officer’s faces, gained access to the prison’s armory, set fire to prison shops and many guards were taken hostage.

Racial tensions were often blamed on the prison riots, which claimed the lives of two people and notable inmates for Auburn include Lucchese crime family mob associate Jimmy Burke and J. Frank Hickey, the Post Card Killer.


46 – Folsom State Prison

Another prison in California, this time located in the state capital, Sacramento, Folsom was the first to have electricity in Prisons.

Grossly overpopulated, like many in the system, over ninety-three prisoners were hanged at Folsom between 1895 and 1937.

Many escape attempts were made before a huge granite wall was constructed around the prison in 1920.

The warden was killed in 1920 and an officer several months later with one of the prisons most famous inmates, Glen Stewart Godwin having a successful escape attempt that landed him on the FBI’s ten most wanted.

Two more inmates escaped in 2010 and incredible violence between gangs such as the Aryan Brotherhood make this one of the most dangerous prisons in California.

Apart from the dangerous nature of life at the prison, its important to note that a considerable amount of California’s licence plates are made here, thanks to several inmate programs.


45 – Robben Island

First used as a prison in the late 17th century, this prison has famously been used as a leper colony in the 1800’s.

Its most famous resident, Nelson Mandela was forced to perform hard labour at the colony and prisoners were often separated by race, with some black prisoners receiving smaller amounts of food.

Located at the entrance to Table Bay, escape was considered impossible thanks to the vast amount of water surrounding the island with at least one escaped prisoner, the victim of drowning.

Much of the prison still remains to this day after it closed at the end of apartheid and it has become a major tourist attraction for the Cape Town Area.


44 – Hanoi Hilton

Housing mainly political prisoners during the Vietnam War, Hanoi’s most brutal prison gets its name mainly from prisoners who were tortured during their incarceration.

Built at the end of the 19th century, the prisons nickname was “Hells Hole” and it was just that with routing beatings, electrocutions and prisoners were often forced to make false statements about their treatment.

None of the guards at the prison were charged after the war, despite claims of the war crimes that took place there and the prison was re-modelled to look nothing like it was during the war.

The prison was partially demolished during the mid ’90s with many parts being turned into a museum and it is also the site of two 25-storey apartment buildings.


43 – Abu Ghraib

Opened in the 1950’s Abu Ghraib prison is located roughly 32 kilometers west of Baghdad and was one of Iraq’s most dangerous prisons.

Weekly executions, torture and poor living conditions under former dictator, Saddam Hussein led to many political prisoners disappearing at the site.

The prison, which closed in 2014, gained international attention in 2003 when more torture and abuse of inmates was released by the media and labeled the perpetrators as guards for coalition forces.

Several mass graves were discovered at the site, thought to have been created by the Saddam Regime with over 101 prisoners being reported killed in one day alone.

All 2,400 prisoners were removed and transferred to other prisons in 2014 after authorities feared ISIL may take over the complex.

Situated high on a hill in the state of Saxony, Germany, Colditz Castle is probably one of the most famous WW2 Prisons.

Made famous by the movie, Escape From Colditz, that followed the real-life escape of sevral prisoners of war, the prison was originally deemed un-escapable.

When the Nazi’s rose to power in 1933, the castle was converted into a prison for political prisoners and later, a high security prisoner-of-war camp for officers who had become security or escape risks.

Prisoners were watched constantly by armed sentries and the walls of the outer courtyard only had two exits.

Surrounded by kilometers of barbed wire, the prison was home to people from many different countries, including Poland, France, Belgium, the Netherlands, Britain and Canada.

The 1,500 guards and agents were armed with machine guns, hand grenades, clubs, whips, and trained dogs to keep the estimated 50,000 prisoners from escaping.
