A worker moves a domino pieces that symbolises a segment of the Berlin Wall in a warehouse in Berlin, Wednesday. As the highlight of a 5-million euro celebration marking the 20th anniversary of the fall of the Berlin Wall on Nov. 9, a 1.5-km (one-mile) long segment of the Wall will stand for two days along its original route in front of the Brandenburg Gate to the Potsdamer Platz. The row of 1,000 20-kg dominos standing 1.5 meters apart - painted in bright colours by school children and rising 2.5 metres high - will be toppled at the end of a gala ceremony as a symbolic tribute to the collapse of the Wall 20 years earlier.
