This is a very large avenue, with walking trails and bike paths on both sides. Where did they get all of this room – from The Wall. There was behind the eastern side of the wall, a 100 meter “killing zone” with machine gun emplacements and obstacles to prevent people from crossing (still, hundreds tried and died in the attempt). There is a lengthy display along this path of photos that show what this route used to look like. The Communists in Germany were only marginally better than the Nazis.
