Diagon Alley is a one-stop destination for all essential supplies needed by a wizard or witch. Step into Ollivanders, Flourish and Blotts, Mr. Mulpepper’s Apothecary, and more to replenish your school supplies. The original architecture and layout of Diagon Alley represent a combination of the rich details from the Harry Potter books along with streets described in the works of author Charles Dickens. The Diagon Alley set features intricately detailed props, shop interiors, and decorations that have undergone significant changes throughout the making of the films. Additionally, the set pieces were re-dressed for Harry Potter and the Prisoner of Azkaban to be showcased as the village Hogsmeade.
