60 years of top secret - today an impressive contemporary witness of Swiss military history: The Crestawald Fortress Museum provides insights into the world of the Cold War. A small village underground.


In September 1939 the construction of the fortress in Crestawald began. In 1940 the huge artillery guns were ready for fire. The aim of this bulwark was to close the north-south transit axis through Graubünden. For a long time, the bunkers carved into the rock were subject to the strictest secrecy. With the restructuring of the Swiss Army and its adaptation to new forms of threat, there was no longer any use for the artillery fortresses near the country's borders. In 1995 the plant was abandoned and in 2000 the secrecy was lifted.

In the same year, the fortress was converted into a publicly accessible museum by the Crestawald Fortress Museum Association. Compared to other artillery works, crestawald Fortress is a small, manageable facility. Thanks to the compactness of the fortress, it is possible to let visitors experience all areas of a fortress up close in a reasonable time. Even older visitors who are no longer so good on foot are welcome in the complex and, with a few exceptions, can visit the entire fortress.

Today, the facility is open to individual visitors or guided tours. The fortress has a seminar room, overnight accommodation (only for groups) and a gastronomic offer in the "Festungsbeizli".

Children (6-16 years) CHF 4.00
