And one of my favorites - "The Magic Mountain" by Thomas Mann. It's set in Davos during the sanatorium days.
I tried watching the euphemistically titled movie "A Short Stay in Switzerland" (it is about a woman who comes here for the purposes of Euthanasia). Did not enjoy it, ended up fast forwarding most of the movie and only watched the shots filmed on location in central Zürich (because it is interesting to see my home town in film).
There are also various documentaries on National Geographic, Discovery Channel etc about the Alps, tunnelling etc. The one I saw about the alps was pretty terrifying, the errosion can result in sudden torrents of rocks cascading down rivers.
