The Hagerbach Test Gallery (VSH) opens its doors to the general public as part of the 50th anniversary of the Swiss Tunnelling Society (STS). Interested visitors can view and experience a large number of underground construction sites and existing underground structures spread throughout Switzerland. 

The multitude of tunnels, caverns, test fields, laboratories and training rooms in the VSH have provided ideal conditions for research, development, testing, 1:1 trials and events of all kinds for over 50 years. A fantastic constellation that is unparalleled. Specialists from all over the world use the VSH as a training camp and research laboratory.
