For this Photo Weekly Challenge I had an “ordinary” idea, but then today I went to the Berlin Wall Memorial Bernauer Strasse and there I had the impression that everything was arranged, starting from the Wall to divide East Berlin from West Berlin to prevent people to flee from one side to the other. Pieces of reinforced concrete arranged together to divide a city, to divide its people.
For some history about the wall check this out: Berlin Wall.
P.S.: I also liked the other idea for the picture, so I might post that one too in the coming days.
