The Berlin Wall was in Europe.
The Berlin Wall ( Berliner Mauer ) was a guarded concrete barrier that physically and ideologically divided Berlin from 1961 to 1989 . Before the Wall 's erection , 3.5 million East Germans circumvented Eastern Bloc emigration restrictions and defected from the GDR , many by crossing over the border from East Berlin into West Berlin ; from which they could then travel to West Germany and other Western European countries .
