For years it was the best kept secret in The Netherlands: a former NATO headquarters inside a mountain on the Dutch-Belgian border during the Cold War. From 1954 till 1992 the quarry was used by the joint forces. (NATO = North Atlantic Treaty Organization)
As of July 1st 1963, also in peacetime, there was a permanent military presence (24 hours a day, all year). From that moment on, some 300-400 Dutch, Belgian, German, English and American soldiers were active during the day, some 40 people at night and more than 1,000 people during multi-day exercises.
This underground network of tunnels, offices and facilities was stripped in 1992 and officially erased.
The former NATO headquarters in the Cannerberg has been opened up after years of remediation.
It can be visited on a monthly basis during one of the weekend excursions.
A team of guides is ready to show you around and tell you about what happened in this part of the Boschberg quarry during the Cold War era.
