The John Lennon Wall was of course once a normal wall, however in the 1980s it started to be filled with John Lennon-inspired graffiti, poems and pieces of lyrics from Beatles songs. The wall now represents symbols of love and peace. It is truly a spot that you must visit to view the graffiti art and read all of the writings both on the wall and in the letters posted on it. You can even be apart of the historical wall yourself by writing an inspirational quote or just leave your mark behind with your name and date, which is of course what I did! Unfortunately some people have chosen to write over some of the paintings (grrrrrr!), so I would recommend writing in places where there is already other written graffiti in order to help preserve the art that makes this wall truly special.
