The Graffiti Tunnel

This guide to the Graffiti Tunnel in London traces the forgotten Eurostar service road beneath Waterloo station back to the May bank holiday weekend of two thousand eight, when Banksy quietly won permission from Network Rail and launched the Cans Festival with thirty-nine artists flown in from around the world. You'll hear about the one rule that governed those three days, and how the authorities responded once tens of thousands of visitors had walked through. Take a slow walk the length of the tunnel and look up as well as ahead.
