Local French oddity becomes INTERNATIONAL MYSTERY!

They don’t have hurricanes or tornadoes in Alsace- never have, likely never will.  So in a recent blog I observed was quite odd for the French to take time from their favorite hobby (namely, wrapping historical buildings in atrocious glass bubbles) to build a nuclear-war-proof bird house, complete with high strength structural steel and (I assume) titanium bolts attached to a deep rebar-reinforced concrete piling:

To me, this was an oddity but no more than that.

But . . . something amazing happened this week. The situation has now suddenly turned from French oddity to international mystery!

For this week I spotted exactly the same type of bird bunker, in a completely different country!

This high strength bird bunker is located near the Zurich airport in Switzerland – and unlike France, outside of the European Union!

So it is now truly an international mystery: who designed this bunker?  Who decided where and when it would be used? Who paid for it? Who maintains it? And especially, when someone decided this was needed, how did they go about sourcing it?  I haven’t checked, but I am pretty sure the local do-it-yourself stores don’t stock massive bird bunkers!
