A complex of over 60 buildings, Beelitz-Heilstatten began life as a sanatorium in 1898. By World War I, however, it became a military hospital for the Imperial German Army, and would have the dubious distinction of treating a young Adolph Hitler in October and November of 1916 when wounded during the Battle of the Somme.
Activity here began during the Prussian Empire.
As the facilities at Peenemunde were being constructed, the war was already taking men and material away from the project. Initially, it was attempted to make the V-2 project a high-priority project, guaranteeing the supplies and manpower required, but since Hitler was still not convinced that rockets were the answer to the war, he vetoed those attempts.
