You see a cathedral...
Turn right.
Go straight on rue LL le Forestier.
Pass intersection with rue Larcher.
Continue straight on rue de Nesmond.
Turn left to allee des Augustines.
Go straight just a little until you see a red gate on your right.

Associate this building with an object.
Find a place on this object which is called "Le retour" in French.

There is a king there...
The name of his grandmother on his mother's side is your password for the next step.
