Reading up on it it could also be in Berlin or Hamburg. The ones in Vienna were in the middle of a park when I was visiting. It was a bit surreal all these families picknicking there, their children running around playing, beneath these enormous military buildings.
It did look similar! I walked through that park at my last visit. And took a photo there too. I think I even saw Piranha but I did not saw it from that side or had the idea that I could see it that way. Nice thanks!
That has to be in Vienna, Austria. They are anti air installations built during ww2
Edit: yep
