The world's worst prisons: Which ones are they and where are they located?

Prisons are institutions for the confinement of persons detained by a judicial authority or who have been deprived of their liberty following conviction for a crime. Thus, a person found guilty of a crime or misdemeanor may be required to serve a prison sentence and, if unlucky, may be sent to one of the worst prisons in the world.

Thus, in most of these places some prisoners do not live to complete their sentence due to brutality and rivalry between inmates.




Generally, in these prisons there is a social hierarchy within each facility, and those at the bottom are most vulnerable, so to speak. There are murders, rapes and attacks on prisoners as well as guards, and the corrupt compliance of some authorities also ensures that the process goes unchecked.

On the other hand, there are normal prisons, but with some more desolate and desperate incarceration facilities that are a real hell. Check out the worst prisons in the world below.

This prison was built in São Paulo in the 1920s and was specifically designed to meet new regulations in Brazil's penal code. However, it was not officially opened until 1956. At its height, Carandiru held around 8.000 prisoners with only 1.000 jailers. Conditions inside the prison were really horrible, as the gangs controlled the environment, while diseases were poorly treated and malnutrition was normal.

The São Paulo prison is unfortunately best remembered for the Carandiru massacre in 1992. The incident was triggered by the inmates' revolt and the police made little or no effort to negotiate with the inmates. The military police were eventually sent to the scene, as the jailers were unable to control the situation. As a result, records show that 111 prisoners died that day, 102 of whom were shot by police, with the remaining nine victims murdered from stab wounds allegedly inflicted by other prisoners before police arrived.

The numbers continued to grow so much so that by 2.000, there were over XNUMX prisoners and overcrowding was an obvious problem.

With the Vietnam War, things got worse as the North Vietnamese Army used the prison as one of their main places to interrogate and torture captured soldiers. They expected American POWs to reveal important military secrets. Consequently, torture methods such as prolonged solitary confinement, beatings, irons and ropes were used, in violation of the Third Geneva Convention of 1949, which defined norms relating to international humanitarian law.

Pitesti Prison was a penal center in communist Romania that was built in the late 1930s. Thus, the first political prisoners entered the place in 1942, and it quickly developed a reputation for bizarre methods of torture. Pitesti earned its place in history as a brutal prison due to the re-education experiments conducted there from December 1949 to September 1951. The aim of the experiments was to brainwash prisoners into abandoning their religious and political beliefs and altering their personalities to ensure complete obedience.
