第十三天：牆

The Berlin Wall (German: Berliner Mauer) was a barrier constructed by the German Democratic Republic (GDR, East Germany) starting on 13 August 1961, that completely cut off West Berlin from surrounding East Germany and from East Berlin. The fall of the Berlin Wall paved the way for German reunification, which was formally concluded on 3 October 1990.
