Halfway down Diagon Alley™ stands an imposing building of snow-white marble: the Bank of Gringotts™ . This is where British witches and wizards store their money and other valuables (including the Philosopher's Stone) in vaults miles underground. Painted and handcrafted with the Gringots™ logo on the back, you too can store your money in one of its most secure magic vaults in the world!
