Scores of cheering Germans on Monday re-enacted the moment the Berlin Wall came crashing down 20 years ago, toppling 1,000 graffiti-adorned 8-foot (two and a half metre) tall dominoes that tumbled along the route of the now vanished Cold War icon. The sequence was set in motion at the Reichstag building by Lech Walesa, Poland's 1980s pro-democracy leader.
It was the finale to a day of memorial services, speeches and events that attracted leaders from around the world, including German Chancellor Angela Merkel and former Soviet leader Mikhail Gorbachev.
Thousands cheered as 1,000 colourfully decorated dominoes along a mile-long (1.6-kilometre) route were toppled to symbolise both the moment the wall came crashing down and the resulting fall of communism in Eastern Europe.
The spectacle finished with a firework display over the Brandenburg Gate, the symbol of Germany's division and then of its reunification, which for nearly three decades stood in no man's land close to the wall. The event was billed by organisers as a metaphor for the way the real wall came down exactly 20 years ago and the resulting fall of communist countries in eastern Europe.
