The Hagerbach NXT 50 festival will take place on 18 June 2021. The Hagerbach Experimental Gallery is a unique facility where engineers and scientists have been developing and testing tunnelling techniques for almost 50 years. Founded in 1970 as a research and development facility for tunnel construction, it has become a place of interest for specialists from all over the world who use its infrastructure as a research laboratory and training ground.


The location of the VSH at Flums, near Sargans in the Glarus Alps, is no accident, as it is situated on the Glarus fault, one of the major fractures in the eastern Swiss Alps. Faults of this type are not uncommon in many mountain ranges around the world, but the Glarus fault is a very accessible example and, as such, has played an important role in the development of geological knowledge about rock mass construction. For this reason, the area was declared a UNESCO World Geological Heritage Site, with the name "Swiss Tectonic Sand Sardona".


Today, the underground network stretches for some 5.2 km and attracts more than 10,000 visitors a year, including a programme of tours and events of various kinds.


To participate both in person and virtually via the Internet, prior registration is required, which will also allow access to the recordings at the end of the event.
