In case you wonder how Switzerland has kept itself from being invaded over the years, here is how.
McPhee points to small moments of "fake stonework, concealing the artillery behind [them]," that dot Switzerland’s Alpine geology, little doors that will pop open to reveal internal cannons that will then blast the country’s roads to smithereens. Later, passing under a mountain bridge, McPhee notices "small steel doors in one pier" hinting that the bridge "was ready to blow. It had been superceded, however, by an even higher bridge, which leaped through the sky above—a part of the new road to Simplon. In an extreme emergency, the midspan of the new bridge would no doubt drop on the old one."
It’s a strange kind of national infrastructure, one that is at its most rigorously functional—one that truly fulfills its promises—when in a state of cascading self-imposed collapse.
I could easily over-quote my way to the end of my internet service here, but it’s a story worth reading. There are, for instance, hidden bomb shelters everywhere in an extraordinary application of dual-use construction. "All over Switzerland," according to McPhee, "in relatively spacious and quiet towns, are sophisticated underground parking garages with automatic machines that offer tickets like tongues and imply a level of commerce that is somewhere else. In a nuclear emergency, huge doors would slide closed with the town’s population inside."
Describing titanic underground fortresses—"networks of tunnels, caverns, bunkers, and surface installations, each spread through many tens of square miles"—McPhee briefly relates the story of a military reconnaissance mission on which he was able to tag along, involving a hydroelectric power station built inside a mountain, accessible by ladders and stairs; the battalion tasked with climbing down into it thus learns "that if a company of soldiers had to do it they could climb the mountain on the inside."
In any case, the book‘s vision of the Alps as a massively constructed—or, at least, geotechnically augmented and militarily amplified—terrain is quite heady, including the very idea that, in seeking to protect itself from outside invaders, Switzerland is prepared to dynamite, shell, bulldoze, and seal itself into a kind of self-protective oblivion, hiding out in artificially expanded rocky passes and concrete super-basements as all roads and bridges into and out of the country are instantly transformed into landslides and dust.
