WALL OF DEATH
At least 136 people, including several children, lost their lives along the Cold War barrier, according to the Potsdam Center for Historical Research.
Some were shot by East German border guards, others drowned in the chilly river Spree.
One of the last to die was Chris Gueffroy. The 20-year-old was shot dead nine months before the fall of the Wall.
Crosses now mark many of the locations where people died trying to reach freedom.
