However urgent archaeological excavations carried out here on a site where a new department store was to be built (this has since been cancelled) uncovered part of the city's medieval fortifications, which are so well preserved that you can still make out the remains of city entrance towers such as the Tour de l'Erdre or the Tour Haut le Pied.
