Government bunker, Military museum in Rhineland-Palatinate, Germany
This site is an underground tunnel system in Rhineland-Palatinate that winds through 19 kilometers of passages now open as a museum. The complex holds 936 bedrooms, 897 offices, and 3,300 steel doors linking corridors carved into the hillside.
Construction began in 1960 and continued until 1972 to create a shelter for federal authorities during the Cold War. The fall of the Berlin Wall made its purpose obsolete, and it later opened to document that era.
Special rooms held equipment for encrypted communication lines that would connect officials across the country, while storage halls stocked emergency rations. Decontamination chambers stood at entry points, and the ventilation system filtered incoming air to protect occupants underground.
Visits run from April through October on Wednesdays, Saturdays, and Sundays from 10:00 to 16:30. The entire site is wheelchair accessible and allows movement through all main sections.
The facility held its own power generators, water systems, and air filters to operate sealed for 30 days. Purpose-built hospital stations with operating rooms stood ready to provide medical care underground.
