John Lennon Wall
In the 80's until the end of communism in 1989, activists would scribble lyrics from Beatles songs, peace signs and slogans, and related artwork on this wall. Here is a description: "The wall continuously undergoes change and the original portrait of Lennon is long lost under layers of new paints. Even when the wall was re-painted by some authorities, on the second day it was again full of poems and flowers. Today, the wall represents a symbol of youth ideals such as love and peace."
