Black Dolphin, Fleury-Mérogis, CECOT, Sednaya or Guantanamo Bay are just a few among thousands of prison facilities worldwide. What sets them apart, however, is the type of inmates they are designed to hold. These and many other such prisons are notorious for detaining some of the world’s most dangerous criminals, including terrorists and the most severe offenders. However, most of these facilities are also infamous for their cruel and inhumane conditions, including maltreatment, torture, and even the killing of prisoners. All of this often occuring with the tacit approval of governments and the indifference of the general public.

Many human rights organisations have repeatedly highlighted the tragic conditions, emphasising that such harsh treatment cannot be anyhow justified. They also point out the persistent failure of authorities to address issues like overcrowding and poor sanitation, which exacerbate the situation and undermine any effort toward humane incarceration or long-term solutions.
