Live from Abu Dhabi Connect the World takes you on a journey across continents, investigating the stories that are changing our world.
Landmark news events come in two forms. There are the 9/11s which we remember for all the wrong reasons and there are the Berlin Walls which we remember for happier reasons.[cnn-photo-caption image=http://i2.cdn.turner.com/cnn/2009/images/11/05/art.berlin.wall.jpg caption="Tell us your memories of the fall of the Berlin Wall."]
The Wall was the focal point of the Cold War which could have ended in disaster but didn't, instead it ended in a street party. The people who celebrated on November 9th 1989 on the rubble of the Wall still struggle to describe that night.
They knew they were witnesses to history but they couldn't fathom the extent of it. Those who weren't there but were watching it on TV from afar had the benefit of expert commentary and probably got their heads round it more quickly. Where were you? What were you thinking?
And what do you think of Berlin today? It's been transformed into a thoroughly modern capital worthy of its reputation as Europe's capital of cool. But has it lost its way and its identity? Former East Germans speak fondly of a devided Berlin with a simpler way of life and a greater sense of community.
Your thoughts on Berlin then and now are our talking points for this week's webcast. Send us comments.
