Lennon wall

The wall continuously undergoes change and the original portrait of Lennon is long lost under layers of new paint. Even when the wall was repainted 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 allowed the graffiti to continue on the wall, and is located at Velkopřerovské náměstí (Grand Priory Square), Malá Strana.
