An Inside Look At The Horrors Of A Soviet-Era Island Prison
This prison was erected (in what is now Estonia) first as a barracks in the time of the Russian Empire, before it was a Soviet state. But, of course, those Soviets needed plenty of prisons, so Patarei was converted into a prison in 1920 and stayed that way until its shutdown in the late 20th century. A quick look inside tells of many horrors. I can’t even imagine (wait, yes, I absolutely can imagine) what type of medical torture was done on these (at times, innocent) prisoners.
