It’s time to visit the Entrance to the Leaky Cauldron in London’s pretty Leadenhall Market. You will realize that the store is actually an optician. 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. This is the birthday of the writer J.K. Rowling and also when Harry found out he was a wizard.
