As written above, I have no images from Berlin-Hohenschönhausen Memorial. – a very sensitive visit. In spite having no images from the museum, I have to write about it below – source is Wikipedia

In June 1945, at the end of WW II, the Soviet NKVD took over the Hohenschönhausen area and transformed it into a detention and transit camp, called Special Camp No. 3. The camp served as both a prison and transfer point. Over 20,000 people passed through Special Camp No. 3 on their way to other Soviet camps.
Living conditions in the camp were deplorable, with death from malnutrition, disease, or common cold. Although official statistics list 886 deaths at the camp between July 1945 and October 1946, independent estimates put the toll as high as 3,000. Bodies were disposed of in local bomb craters.
The camp was closed in October 1946. After the closing, the Hohenschönhausen compound served as a Soviet prison during the winter of 1946–1947.

The prison was reopened by Stasi in 1951 The Stasi added a new prison in the late 1950s. In the beginning, the prison was primarily used to house those who wished or attempted to leave East Germany, although political prisoners were also held there. The prison closed on 3 October 1990.
The main prison also included a hospital wing. The hospital treated prisoners from Berlin prisons and sometimes from other Stasi prisons as well. The hospital had up to 28 beds, treatment, operating rooms, a morgue, and outdoor exercise cells.

Hohenschönhausen was a very important part of East Germany’s system of political oppression.
Although torture and physical violence were commonly employed at Hohenschönhausen, 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 cells that could be filled with water to prevent the prisoner from sitting or sleeping.
The prison was located in a large, restricted area bordered by a large military town, so it was difficult for the local people to discover what was going on. Officially it did not exist during many of the years it operated, being left off all maps.
Today, much knowledge comes from former prisoners’ personal accounts and documentation from other East German institutions.
