Печенгский район
In 1944, the Red Army occupied Petsamo, and Finland had to cede it to the Soviet Union as part of the Moscow Armistice signed on September 19, 1944. Retreating German forces destroyed the power plant and partially the smelter. On July 21, 1945, the Presidium of the Supreme Soviet of the Soviet Union decreed to establish Pechengsky District with the administrative center in Nikel on the ceded territory and to include this district as a part of Murmansk Oblast.
