Gringotts Wizards' Bank was the only bank in the wizarding world, in which wizards kept their money. It is run by goblins. On 31 July, 1991, there was a break-in (secretly led by Quirrell and Lord Voldemort) at this bank. Harry Potter and Rubeus Hagrid travelled here together on 1 August, 1991 to collect money from Harry's vault to pay for his school supplies.
