List of Gulag camps

It is estimated that for most of its existence, the Gulag system consisted of over 30,000 camps, divided into three categories according to the number of prisoners held.

[2] There were a number of particular categories of convicts that were imprisoned there including: The prisoners of war were generally imprisoned in special POW camps, which existed independently from the network of corrective labor camps, and were subordinated to a separate administrative apparatus within the NKVD (since 1946: MVD) called GUPVI.

Unlike Gulag camps, located primarily in remote areas (mostly in Siberia), most of the POW camps after the war were located in the European part of the Soviet Union (with notable exceptions of the Japanese POW in the Soviet Union), where the prisoners worked on restoration of the country's infrastructure destroyed during the war: roads, railways, plants, etc., see POW labor in the Soviet Union.

Polish citizens and members of other nationalities who were imprisoned at the Soviet forced labour camps during World War II worked also for the Soviet Army, digging trenches, employed in lumber and cement works, airport runway construction, and unloading of transport goods.
