Dome

Base of the precast concrete wall; The Berlin Wall (German: Berliner Mauer) was a physical barrier completely encircling West Berlin, separating it from the German Democratic Republic (GDR) (East Germany), including East Berlin. The wall separated East Germany from West Germany for more than a quarter of a century, from the day construction began on 13 August 1961 until the Wall was brought down on 9 November 1989. The fall of the Berlin Wall paved the way for German reunification, which was formally concluded on 3 October 1990. A portion of the Berlin Wall has been given by the city of Berlin to the city of Montréal in 1992 for its 350th birthday. The portion comes from a location near Brandenburg Gate and is now displayed in the Centre de Commerce mondial de Montréal (World Trade Centre Montreal).
