City of London, England
Leadenhall Market
Diagon Alley and the Leaky Cauldron
The ornate covered passages of Leadenhall Market became part of Diagon Alley in Harry Potter and the Philosopher's Stone. In Bull's Head Passage, the blue shopfront used as the entrance to the Leaky Cauldron can still be identified among the working businesses.
