About Annecy
Learn more about the host city, Annecy.
Annecy, in the north of the French Alps, is called "the Venice of Savoie" — a well-deserved title. The medieval town centre built around a 14th-century chateau is dissected by small canals and streams running out of Lac Annecy, which is clean, fresh and a wonderful azure colour. Annecy is the prefecture of the département of Haute-Savoie.
