Berlin Wall

The Berlin Wall was a guarded concrete barrier that physically and ideologically divided Berlin from 1961 to 1989 as well as encircling and separating West Berlin from East German territory. Construction of the wall was commenced by the German Democratic Republic on 13 August 1961. The Wall cut off West Berlin from surrounding East Germany, including East Berlin. The barrier included guard towers placed along large concrete walls, accompanied by a wide area that contained anti-vehicle trenches, beds of nails and other defenses. The Eastern Bloc portrayed the Wall as protecting its population from fascist elements conspiring to prevent the "will of the people" from building a socialist state in East Germany.

GDR authorities officially referred to the Berlin Wall as the Anti-Fascist Protection Rampart. The West Berlin city government sometimes referred to it as the "Wall of Shame", a term coined by mayor Willy Brandt in reference to the Wall's restriction on freedom of movement.
