Artillery fort of Champex-Lac


A fascinating world, in the heart of the mountains with a strange atmosphere – a hidden fortress under the Alps. Champex-Lac Artillery Fort constitutes a central pillar of the fortifications in the Grand-Saint-Bernard region.

Built in 1940 and 1943, modernised and adapted for a possible nuclear conflict during the Cold War period, the work was used by the Swiss army until 1998. More than 600 metres of tunnels dug into the mountain. Totally invisible from the outside, the fort was able to house 300 men.
