During the last few years, this annual STS event has developed into the main congress for tunnelling experts in Switzerland, originally evolving from the AlpTransit congresses. There are annually around 800 experts from 15 nations attended the high-quality presentations and additionally enjoyed the traditional excursions to large construction sites within Switzerland and the surrounding area which took place.

The STC 2023 will be held in its proven form, consisting of a colloquium, congress, exhibition, evening events and excursions.

This year, the Swiss Tunnelling Society celebrates its 50th anniversary. 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. https://www.einblick.swisstunnel.ch/en
