Premise: Berlin ( [ bəɹˈlɪn ] , [ bɛɐ̯ˈliːn ] ) is the capital and the largest city of Germany as well as one of its 16 constituent states . The Berlin Wall ( Berliner Mauer ) was a guarded concrete barrier that physically and ideologically divided Berlin from 1961 to 1989 . Constructed by the German Democratic Republic ( GDR , East Germany ) , starting on 13 August 1961 , the Wall completely cut off ( by land ) West Berlin from surrounding East Germany and from East Berlin until government officials opened it in November 1989 .
Hypothesis: The Berlin Wall was in Germany.
