25 years of the wall coming down - the Lichtgrenze is being lifted
In 2014, for the celebration of the 25th anniversary of the wall coming down, there was a special art installation created in Berlin, which was called "Lichtgrenze". For this, the wall was being recreated in the form of lights, being held by thousands of people, who would release them one after the other at the hour the wall actually came down in 1989.
The picture shows the releasement passing the Marschallbrücke in front of the Reichstag.
