Of what awaits the sin of greed,
For those who take, but do not earn,
Must pay most dearly in their turn.
So if you seek beneath our floors
A treasure that was never yours,
Thief, you have been warned, beware
Of finding more than treasure there."
—Inscription on the doors of Gringotts
"Gringotts Wizarding Bank is the only known bank of the wizarding world, and is owned and operated by goblins. It was created by the goblin Gringott. Its main offices are located in Diagon Alley in London, England. In addition to storing money and valuables for wizards and witches, one can go there to exchange Muggle money for wizarding money. According to Rubeus Hagrid, other than Hogwarts School of Witchcraft and Wizardry, Gringotts is the safest place in the wizarding world."
