It’s time to visit The Leaky Cauldron in London’s pretty Leadenhall Market, Harry Potter’s Diagon Alley. You will realize that the store is an optician actually. Remember this is the iconic spot of the conversation between Harry and Hagrid: “Can we find all this in London?” “If you know where to go!”
Leadenhall Market is a covered market in the City of London, designed in 1881, with cheesemongers, butchers, florists, and some commercial retailers. Harry Potter and Rubeus Hagrid passed through Leadenhall Market on their way to the Leaky Cauldron and Diagon Alley on 31 July, 1991. It’s the birthday of the writer J.K. Rowling and also when Harry found out he was a wizard.
