I came across the John Lennon wall in Prague when I was staying in Mala Strana taking my father to see his family. I was so taken by the baroque buildings on my way to Kampa Park that the site of this wall was a strong contrast to the nearby French embassy. During the 80’s after his death and before 1989, students would put graffiti up each night and it became a symbol of free speech. Since pop music as actually banned, he was even more of a hero at that time. Even now, it has a very powerful effect.
