To the strains of Beethoven's Ninth Symphony in the presence of guests of honour and eyewitnesses at the Brandenburg Gate and at six other locations, white balloons will be released into the skies on the night of 9 November to commemorate the peaceful revolution of 1989 and the fall of the Berlin Wall 25 years ago.
