In the early morning hours of August 13, 1961, GDR border troops and workers began erecting barbed wire and makeshift barriers along the border to West Berlin. This drastic measure was called the "Anti-Fascist Protection Wall" by the GDR leadership, whose alleged purpose was to protect the GDR from Western aggression.
The real reason for building the wall, however, was the massive emigration of citizens from the GDR to the West. Between 1949 and 1961, about 2.7 million people had left the GDR, leading to a serious shortage of labor and a demographic crisis. Most of these refugees were young, well-educated people whose loss significantly weakened the GDR economy.
In the following years, the original barricade was replaced by an increasingly complex fortification system. The final version of the Berlin Wall consisted of:
- A 3.6 meter high concrete wall on the western side
- A "death strip" with anti-tank ditches, signal wires and patrol paths
- A second, lower wall on the eastern side
- 302 watchtowers and 20 bunkers
- Automatic firing devices and other deadly barriers
The total length of the Berlin Wall was 155 kilometers, of which 43 kilometers ran through the middle of the city. The wall not only separated a city, but also families, friends and an entire people.
