베를린 장벽 붕괴를 기념하는 등불 장벽 행사 : Lichtgrenze 2014: Commemorating the Fall of the Berlin Wall

Numerous events were held this weekend across Berlin, Germany, remembering the November 9, 1989 fall of the Berlin Wall that once divided the city. A project called "Lichtgrenze 2014" (literally "Lightborder 2014") was erected, temporarily dividing the city once more with a line of 8,000 illuminated balloons along the 9.5 mile (15.3 kilometer) path once occupied by the Berlin Wall. The weekend was capped off by a large concert at Brandenburg Gate, attended by thousands.           11/09/2014
