Chablais

Chablais was a former province of the Duchy of Savoy, with its historic capital in Thonon-les-Bains.

This region is currently divided into three territories, the Chablais savoyard, the Chablais valaisan, and the Chablais vaudois, and is now split across two countries: France (department of Haute-Savoie) and Switzerland (cantons of Valais and Vaud). The Chablais Alps is a mountain range situated between the two countries.
