The Berlin Wall
was erected in the night of August 13, 1961.
It was a weekend and most Berliners slept
while the East German government begun to close the border. In the early morning of that
Sunday most of the first work was done: the border to West Berlin was closed. The East
German troups had begun to tear up streets and to install barbed wire entanglement and
fences through Berlin.
The first concrete elements and large square blocks were used first on August 15, 1961.
Within the next months the first generation of the Berlin Wall was build up: a wall
consisting of concrete elements and square blocks.
A second Wall was build in June 1962 in
order to prevent from escaping to the West.
The first Wall was improved during the next years and it's difficult to distinguish
between the first and the second generation of the Wall.
These two first generations were removed by the third generation beginning about 1965. The
third generation of Wall consisted of concrete slabs between steel girder and concrete
posts with a concrete sewage pipe on top of the Wall.
From the year 1975 the third generation of Wall was replaced by the fourth generation. New
concrete segements were used which were easy to build up and were more resistant to
breakthroughs and to environmental polutions.
