The Lennon Wall was formerly an ordinary wall in Prague, but since the 1980s, people have filled it with John Lennon-inspired graffiti and pieces of lyrics from Beatles songs.
In 1988 the wall was a source of irritation for the then communist regime of Gustav Husak. Young Czechs would write grievances on the wall and in a report of the time this led to a clash between hundreds of students and security police on the nearby Charles Bridge. The movement these students followed was described ironically as Lennonism and Czech authorities described these educated peaceful people variously as alcoholics, mentally deranged, sociopathic, and agents of Western capitalism.
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.
The wall is owned by the Knights of the Maltese Cross, who graciously allowed graffiti to continue on what actually is a lovely Renaissance wall, and is located at Velkopřevorské náměstí (Grand Priory Square), Malá Strana.
