Political oppression
Hohenschönhausen was a very important part of the GDR's system of political and artistic oppression.
Although torture (including Chinese water torture) and physical violence were commonly employed at Hohenschönhausen (especially in the 1950s), psychological intimidation was the main method of political repression and techniques including sleep deprivation, total isolation, threats to friends and family members, and the use of water cells.
