Gringotts

The one and only wizarding bank, Gringotts is a large and imposing marble building at the end of the alley. The bank is run by goblins, and has the tightest security of any place on earth. Only one break-in has ever been successful, and since then any and all gaps have been closed. Gringotts also offers an exchange program that allows wizards to turn Muggle money in and receive Galleons, or vice versa.
