The SS established Neuengamme in December 1938 as a subcamp of Sachsenhausen concentration camp. It was located on the grounds of an abandoned brickworks on the banks of the Dove-Elbe, a tributary of the Elbe River in the Hamburg suburb Neuengamme, in northern Germany.
Investing through the SS-owned German Earth and Stone Works Corporation (Deutsche Erd- und Steinwerke), SS leaders intended to reactivate and renovate the brick works, using concentration camp laborers. On December 12-13, 1938, the SS brought about 100 prisoners from Sachsenhausen to the site to begin construction of the camp. The first prisoners were housed within the factory itself.
