A reinforced concrete bunker located near Lübeck, Germany, constructed during World War II as part of the Nazi V-2 rocket program. The structure served as a test stand for ballistic missile development and was part of the Peenemünde research complex. Its purpose was to simulate launch conditions for the A-4 rocket (V-2) before deployment.
The bunker's design included thick walls and reinforced ceilings to withstand the intense vibrations and pressures of rocket testing. It is situated in a region historically significant for German military rocketry research during the 1940s.
