Kamiti Maximum Security Prison, Nairobi, Kenya
Situated on a 1,200 acre lot, this prison has gained notoriety due to the unspeakable squalor that the prisoners are subjected to.

Butyrka Prison, Moscow, Russia
The largest central transit prison of Moscow is known for its brutality. It held 20,000 inmates during the Great Purge and thousands of them were executed after investigations. Its administration also resorted to violence every time the inmates tried to protest against anything. Besides the problem of overcrowding, as there could be up to 100 inmates in cells intended only for 10 people, it is extremely hot in the summer and also has problems with epidemics such as AIDS and tuberculosis.
Nairobi Prison, Kenya
Built in 1911 for 800 prisoners, which boomed to 3,000 in 2003, this prison is one of the most congested in the world. This congestion not only resulted in overcrowding, but also in problems with hygiene, sanitation, and general living conditions where it would be a struggle to be physically and mentally healthy. The prison cells reek of sweat, human waste, and filth with the stench of garbage hanging in the air.
Black Beach Prison, Malabo, Equatorial Guinea

Petak Island Prison, White Lake Russia
This is the Russian version of Alcatraz, as it was isolated by the White Lake and was built to hold the most dangerous prisoners. Though they never have to fear violence from the guards or their inmates, the restricted life of living in cages and in isolation with no lavatories nor washing facilities surrounded by freezing cold water and snow leaves the prisoners to deteriorate and become psychologically devastated.
