Norman Switzerland (French: Suisse Normande) is a part of Normandy, France, in the border region of the departments Calvados and Orne. Its name comes from its rugged and verdant relief resembling the Swiss Alps, with gorges carved by the river Orne and its tributaries, and by erosion in the Armorican Massif between Putanges-Pont-Écrepin and Thury-Harcourt.
