4. Diagon Alley and the Leaky Caldron Pub
While Diagon Alley was mostly a film set creation, some exterior shots were taken around London’s Leandenhall Market and Borough Market. Walking around here gives you a feel that you just might stumble upon a porthole to the wizard dimension. The Glass House Opticians at 42 Bull’s Head Passage in Leadenhall was the first location of the Leaky Caldron pub, where Harry and Hagrid entered the magical realm. In The Prisoner of Azkaban the Leaky Cauldron location moved to Chez Michelle flower shop in Borough Market. This is where the Knight Bus pulled up and Harry got off.
