This is an old strategy, nowadays the army works differently. But still, these are interesting tidbits of history. Many old bunkers have been decomissioned and taken over by associations preserving them as museums. Others are opened for the public like the Great War's bunker just below the top of the Sigriswiler Rothorn (Schafloch). Instead of hiking over the top I just went through it with my son. It was very dark, labyrinthine and scary. My son loved it.
