To celebrate the 25th anniversary of the fall of the Berlin Wall, an extraordinary light installation appeared in Berlin on 7 November 2014. The Lichtgrenze (Border of Lights) saw 8,000 balloon pillars set up along the former 15.3 kilometre course of the Wall. In a televised spectacle on 9 November, volunteers performed a choreographed release of the balloons, sending them winding one by one into the night sky. With the help of the Berlin people, the Wall of Light, just like its 1989 counterpart, completely disappeared.
