Guérande is a medieval town located in the department of Loire-Atlantique, and the region of Pays de la Loire, Western France. The inhabitants are referred to as Guérandais, and Guérandaise. The Guérande Peninsula overlooks two contrasting landscapes: the "Pays Blanc", because of its salt marshes, and the "Pays Noir", with the Brière peat bog. The town's salt marshes have made it a renowned producer of salt, and it is the traditional source of fleur de sel, a type of garnishing salt.
