There is a secret garden down a cobbled side street in front of a desolate church in London. It is a place of sanctuary amongst all the noise and bustle of the capital and I feel like I step back in time whenever I park myself down on a bench. It’s my secret place but if you want to visit enough then do a little research and you can enjoy it too!
When it is time to leave I pass this sign (your clue). It always makes me smile.
