Has anyone ever visited the Leake Street Tunnel to see the graffiti works there? I saw it on a list of 101 free things to do in London and it looks pretty amazing. https://www.instagram.com/p/BQR8douBiE-/?utm_source=ig_embed
WHdether it is worth going out of your way is up to you, depends where you are. As we regularly stay in Lambeth we have had the opportunity to choose to through this several times as a matter of course, and if you are into these displays you should enjoy it.
Thank you. It looks fascinating and we will be close in our travels around London.
