On the left side of the bridge on the Mala Strana side there is a small island called Kampa, which is a calm oasis away from all, or at least most of, the tourists on the Charles bridge. There we found a wall with loads of grafitti. We found out later that it's called the Lennon wall. During the communist era it was here that revolutionaries daubed anti-government slogans, running the risk of arrest. Today the wall is covered with graffiti - poems and words of peace written by millions of visitors from around the world.
