Look on DDR

I was a child when the wall of Berlin falled. Today, i'm 39 and i always lived in France, accross the boarders with Germany. Surprising neighbors, ennemy became a friend, so near and sometimes so far. I know well west germany but, a few kilometers further, life is she still different ? Is there always a wall between the country, between our continent ? What traces of the communism are still in Landscapes and cities of the former DDR ? What remains and what changes ? What East of Germany looks like today ? Let's go there.
