Gringotts is white, multistory, marble building that towers over the neighboring shops. It is located partway down Diagon Alley, near its intersection with Knockturn Alley. It is the place where British witches and wizards store their money and other valuables, in heavily-guarded vaults miles below ground.
From Diagon Alley, a set of white stairs leads up to a set of burnished bronze doors. The doors are flanked by a goblin in a uniform of scarlet and gold. This is the entrance to Gringotts, and it leads into a small entrance hall and another set of doors. Engraved on these silver doors are the words:
Enter, stranger, but take heed
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.
Through these doors, also flanked with goblins, is a vast marble hall long counters stretching along its length with doors leading off to the vault passageways with around a hundred goblins sitting at them.
At Gringotts you can exchange Wizarding money for Muggle money, and visa verse. Click here to see the exchange rates.
You can also exchange foreign currencies, both magical and Muggle.
We are also willing to exchange any coins that are equal in value. For example, 34 Sickles for 2 Galleons.
In contrast to the grand marble of the entryway and the main hall, the passageways to the vaults are stone and dimly lit with flaming torches. They slope down to a track, upon which run little carts controlled by the goblins. These carts take visitors deep beneath the surface of the earth, through a maze of twisting passages, to the vaults. The carts go very quickly, which makes some people a little queasy and prevents its occupants from getting a good look at their surroundings. The carts seem to run on a vast, complex, interconnected series of tracks that allow them to move to and between any vaults.
The vaults themselves vary in size and security. The largest, most well protected vaults belong to the oldest wizarding families and lie deepest beneath the surface. Those vaults closer to the surface seem to be smaller and have fewer security precautions surrounding them - they use keys, for example, rather than requiring the touch of a goblin to gain access. The rules around who is allowed to access vaults seem to change; sometimes wizards are asked for identification or a key to be allowed access, other times trusted friends are allowed to get gold for each other.
Only blood relations can inherit a Gringotts vault, although gold from those vaults can be inherited. The gold is moved to the person who inherited it's vault, rather than the actual vault itself being inherited.
