Surviving Underground – guides tours of  the Sonnenberg civilian bunker
On a 2-hour tour you will experience Sonnenberg, one of the world’s largest civilian bunkers, located in the heart of the city of Lucerne!
This giant bunker was built between 1970 and 1976 at a cost of 40 million Swiss francs. Had it ever been needed, two highway tunnels would have been sealed off by four 350-ton concrete blast doors and transformed into a bunker with room enough for 20,000 beds and hundreds of toilet cabins and sinks. In fact, one third of the population of Lucerne would have found shelter inside Mount Sonnenberg.
To complement the bunker, a seven-storey underground building surrounding the motorway tunnels was built, serving as the logistical and technical command facility for the shelter. This consisted of a command centre, a radio studio, an emergency hospital, detention cells and much more.
The guided tour provides a fascinating insight into the Cold War and the Fear of the nuclear bomb and illustrates the use of the bunker today.
