The Berlin wall was built to separate the Eastern part of Berlin, which embraced communism during the cold war, from the Western part of Berlin which did not embrace communism.

The fall of the Berlin wall in 1989 was one of the clearest signs of the fall of communism, which was associated with great repression of human rights.

Though much of Berlin wall was demolished to signify the unification of Berlin, Vestiges of the wall are still visible in the city.

A good place to check out the Berlin wall is at the Mauerpark (Wall Park) museum, and Checkpoint Charlie at Friedrichstrasse 43-45 – which at the height of the cold war was an infamous border crossing point between East and West Germany.
