Prisons are far preferable than they were once, but none equates to freedom, so this post is about to reveal most of the most dangerous prisons in the world, which are best avoided.

Prisons did not start as routinely as they are today, but only as a conjunction of detention centers. This implies that it was used to house both convicted and sentenced culprits along with folks facing trial, and the prisoners were a mix of kids and adults.


History Of Prisons

The oldest recorded prisons date back to the first millennium BC, with locations in ancient Mesopotamia, Egypt, and ancient Rome, where the underground prisons had cells that were too tiny for human bodies, requiring them to be situated in one place or bent over for long periods.

Except in ancient Greece, where prisoners were detained in shabby buildings with wooden shackles around their feet and where they could be visited by friends and family, prisons were almost always underground dungeons.

The most significant consequence for such prisoners was death or slavery, and special slaves in Rome were forced to fight and kill as a business for their masters, the well-known Gladiators.


Prisons as we know them today, on the other hand, became popular during World War II when people were apprehended in hundreds of facilities and then executed without any form of trial.
