Russian criminals have a reputation around the world for being totally fearless and insanely violent. So what are things like inside a prison that holds the worst of the worst? Welcome to Penal Colony 56, also known as Black Eagle. In this maximum security facility located in the northern Ural mountains, every single one of the 260 inmates was serving a life sentence. Child murderers, terrorists, contract killers, serial rapists and more fill the cells in this insanely strict facility. Inmates are kept alone in their rooms for 23 hours a day and can go to "the yard" -- a concrete room with no ceiling -- either alone or in pairs for the remaining hour. There is no sewage system and in winter the entire area disappears under ten feet of snow with -45C temperatures. A third of the inmates go insane from the deprivation.
