When it became clear that the Nazi were losing control of the air space above Germany and Austria, their heartland, they decided to build so-called “Flak Towers”, named after the abbreviation of “FLiegerAbwehrKanone” (air-defense cannon).
Not that it helped much, and they knew it wouldn’t help, but those monumental (and monumentally ugly) structures of concrete were at least impressive, looked mighty, in other words, it was propaganda again.
Eight such pairs were built, three in Berlin, three in Vienna and two in Hamburg. They are ugly as hell, but they were constructed to withstand massive bombardment, thus it would be almost impossible to tear them down, and so they stand and remind us of Nazi barbarism.
For illustrative purposes I’ve added three JPEGs fresh from the camera. Enjoyment would be the wrong word 😀
