Medieval town enclosed by fortification walls from the 14th and 15th centuries, protected by 6 towers and moat, Guérande can be entered through one of six massive gates, like the impressive Saint-Michel Gate. The area is most famous nationwide for its production of a delicious sea salt. 5.000 acres of salt marshes where the sea enters at high tide and where the water evaporates naturally have allowed the salt-panning industry to continue since the 15th century
