The Wizarding Bank
Gringotts is the wizarding bank in the Harry Potter films and books. It is located in London, more precisely in the Chemin de Traverse, a magical street to which only wizards who know the secret passage can access. Harry discovered it before the beginning of his first year at Hogwarts when Hagrid took him there to show him all the money his parents had saved for him. This bank is run by goblins, rather cold and unpleasant magical creatures who are very good with numbers and at forging very strong weapons and chests. The chests are accessed by presenting your key and then taking a rather dangerous looking little wagon on rails. Harry has to deal with the goblin chief when he comes for the first time but also when he comes back in the last movie to enter Bellatrix Lestrange’s safe.
