Leake Street Graffiti Tunnel - Leake Street, Lambeth, London, England, United Kingdom

It was here that the iconic and secretive artist Banksy held the first Cans Festival in May 2008. With the event, Banksy personally invited street artists to practice their craft in the pedestrian only tunnel. While graffiti is normally frowned upon and can lead to an arrest, graffiti artists can work here to their hearts’ content.
