Fascinating insight into the cold war era


The top secret, well-hidden and protected bunker in the rock Alvaneu was the command center of the Border Brigade 12 and the military center in the strategic center of the canton of Graubünden. The visit offers a unique insight into the completely autonomous facility – not only for those interested in military affairs. How did the internal energy supply work? Where did the fresh air come from ... and the water? How did you protect the crew from a gas attack or a nuclear strike? How were the daily work and processes organized 200 meters deep in the mountain? How did the communication to the outside world work? Was there a worst-case scenario? All these questions will be answered.

Immerse yourself in the processes of the command bunker, electronically supported with the specially designed augmented reality on an iPad. Discover your military-strategic talent in a playful way...
