Germany

Beelitz

History: 

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.

Versuchskommando Nord Barracks

History: 

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.
