      That has to be in Vienna, Austria. They are anti air installations built during ww2

      Edit: yep

      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.
