Insight into the underground

In the anniversary year 2023, the general public will be given access to well-known and lesser-known, exciting structures under the heading "Insight into the Underground". As part of the 50th anniversary of the Swiss Tunneling Society (STS), anyone interested can visit and experience a large number of underground construction sites and existing underground structures in 5 clusters/regions spread across Switzerland.

The public should be able to see

...what lies behind the infrastructure used on a daily basis.

…how the underground can be used in even more ways.

…how fascinating underground construction is.

…how security is guaranteed.

...which challenges planners, contractors and maintenance are faced with.

Switzerland was divided into the following 5 clusters/regions, in which various underground construction objects can be visited on the following dates:
