This might be a stupid question, but isn't Switzerland known for its countless hidden bunkers and defense positions? Doesn't mapping and publicly exposing basically the whole country only bring negatives and nothing positive?
Besides that it's hard to imagine which foreign power would have incentive and power projection to even try it.
The way I've understood it is that none of their defense is hidden, it uses the natural and societal benefits. Most of that could be gleaned by anyone with access to satellite images and wikipedia.
That might all be outdated info though, it'd be interesting to see where I'm wrong though!
I'm guessing other European countries did this too.
Surely this was before nukes? After reading “nuclear war: a scenario”, I’m really not sure there’s much use surviving the initial blast anyway.
Here's a cute video I found discussing the line of 12 fortresses protecting a little bottleneck of a river valley - he explains that the two camouflaged as villas are done so as not to be eyesores for the tourists.

EDIT a few more examples here
A former infantry bunker is camouflaged as a medieval house in the town of Duggingen. Notice the half-circle windows, which appear to have been painted on
Nearby mountains have been made so porous that whole divisions can fit inside them. There are weapons and soldiers under barns. There are cannons inside pretty houses.
If you look closely, you can see a massive door in the hillside that would swing open - A Swiss Air Force Mirage III RS outside its mountain hanger.
All built around 1930s. There is popular hiking trail along all this, since nature and forests around it are pretty and well maintained. No secret really. Same for many other old stuff. New stuff should be hidden on bases/remote places.
Btw checked our building and surrounding ones and its pretty precise but not up to date with 2024 finished construction.
