Hirschhagen is a district of Hessisch-Lichtenau and idyllically situated in the Kaufunger Forest, near Kassel, Germany. While exploring Hirschhagen you will notice the special, peculiar construction of many buildings and the ruins in the village. Structures made of reinforced concrete in frame construction, oversized plinths, massive, overhanging flat roofs, some of which are planted with trees. From 1936 to 1945, the National Socialists had built and operated one of the largest explosives and powder factories in the German Reich here under the trivialising camouflage name "Friedland". After the war, the factory was dismantled and part of the buildings blown up. Other houses were gradually rebuilt for commercial and residential use. Today Hirschhagen has over 200 inhabitants. A special form of the peaceful use of places of war production. At home in a former explosives factory.
