Graffiti on Berlin Wall (juan), originally uploaded by Teign Photography.This is one of a series of photos that I took of the Graffiti on the old Berlin Wall. This section of the wall which is known as the East Side Gallery is 1.3.km long and runs next to the River Spree. It is covered by art work from artists across the world and is a memorial for freedom. I believe it is the largest open air gallery in the world.
