Diagon Alley

In J. K. Rowling's Harry Potter novels and their filmed adaptations, Diagon Alley is a fictional alleyway in London accessible to witches and wizards but invisible to muggles, containing numerous shops selling magical supplies. These include Flourish & Blott's (a bookstore), Ollivander's (makers of magic wands[?] since 382 BC) and Eeylops' Owl Emporium. The Alley is also home to The Leaky Cauldron Inn, and Gringott's Bank, which is run by goblins.

In the film Harry Potter and the Philosopher's (aka Sorcerer's) Stone, Diagon Alley appears to be a short walk away from Leadenhall Market[?] in the City of London.

The name is a pun on "diagonally" (if proof of this is required it can be found in the movie version of Harry Potter and the Chamber of Secrets.)

Leading off of Diagon Alley is the dark and dingy Knockturn Alley.

The DVD of the movie Harry Potter and the Chamber of Secrets (2002) includes a video "guided tour" of Diagon Alley, apparently shot on the original movie set.
