Harry Potter Free Walking Tour

This tour starts at the Palace Theatre on Shaftesbury Avenue, where Harry Potter and the Cursed Child has kept the story running on stage long after the last book closed, then turns central London into a map of the wizarding world's real-world inspirations. Expect the Georgian bookshops and antique print sellers of Cecil Court, long rumored to have shaped Diagon Alley's look, the marble banking hall inside Australia House that became Gringotts on screen, and the covered Victorian arcades of Leadenhall Market, dressed up as the alley's entrance for the first film.

Your guide separates genuine filming locations from pure fan folklore — London has plenty of both — and points out details easy to miss without someone who has read the books more than once. It's an easy, mostly flat walk built around photo stops rather than trivia lectures, equally suited to lifelong Potterheads and the friends and family they dragged along.
