Partway down Diagon Alley, near its intersection with Knockturn Alley, stands an imposing snow-white marble building: Gringotts Wizarding Bank. It is the place where British witches and wizards store their money and other valuables, in vaults miles below ground. The vaults are heavily guarded. The centuries-old bank is run by goblins, and they alone know the secrets of the twisting underground passages and the enchantments in place to defend against intruders.
