Page 3- The Reality of the Wall
The Wall went through many stages as time passed. It was gradually perfected and became more and more impenetrable. It was eventually revamped four times. Initially, it was made up of 12 km of concrete slabs and 137 km of barbed wire, surveyed by 116 watch towers. They also bricked up the windows of some buildings that were close to the wall, like those on Bernauer Strasse. It eventually became two walls: the one covered with graffiti seen from the West and a parallel wall that was seen from the East. In between the two walls was 30-100 yards of carefully

tended earth (so footprints could be easily seen), a small paved road for soldiers, and watchtowers. This space was known as no-man’s land. The top of the wall was covered in a rounded tube to prevent people and grappling hooks from catching hold of it. As a further precaution, the eastern side of the wall was painted white so that anyone trying to scale the wall could easily be spotted. In the final phase of the wall, there were anti-tank ditches, anti-vehicle ditches, 600 dogs on sliding cables, and 14, 000 border guards.
