Diagon Alley is a shopping area, located in London, England. Hidden behind muggle eyes Diagon is accessible through The Leaky Cauldron. Behind The Leaky Cauldron is a small courtyard, tapping on the brick wall in the correct pattern will reveal the entrance. Diagon can also be accessed by use of floo powder and apparition.

The Alley is connected to Knockturn Alley, a shopping place known for its shops dedicated to the Dark Arts.
