Back in 1961 the Berlin Wall was built to prevent the people of East Germany from fleeing to the West during the Cold War. By 1990 the 4m-high wall extended up to 155km, dissected 55 streets, and possessed 293 observation towers and 57 bunkers. Near the center of Berlin, a section of the infamous wall has become a memorial in the form of graffiti. Featuring the talented work of over 100 international artists, the East Side Gallery is one of the largest outdoor art exhibits in the world with the theme – freedom. Sections of preserved wall include a short stretch at infamous Checkpoint Charlie and at Humboldthafen on which the 70 victims who had tried to escape the wall back in the day are listed.
