Diagon Alley is the main place for you to shop for magical items in the UK. Connected to Knockturn Alley, it houses a shop for almost any thing imaginable and also has its own bank- Gringotts. It’s not uncommon to see students here during holidays and other then Floo Powder it can be reached by passing through the Leaky Cauldron. The main attraction just recently is Weasleys’ Wizard Wheezes- run by the Weasley twins it has any trick imaginable.
