The mountain - limit and border, impervious barrier that divides, seems to launch a challenge to overcome it. The Sempioniani Museum tells the story of this millenary challenge, from the prehistoric steps of daring solitary traders to the construction of the Simplon tunnel, from Napoleon to Geo Chavez, the first heroic and unfortunate flyer of the Alps. An innovative and interactive exhibition accompanies the visitor to the discovery of one of the most important Alpine passes and of the technology deployed to win the mountain challenge.
