Agglomeration community of Annemasse – Les Voirons
In 1966, the communes of Ambilly, Annemasse, Etrembières, Gaillard, Ville-la-Grand and Vétraz-Monthoux formed the syndicat intercommunal à vocations multiples of the Annemasse agglomeration. This cooperation became a communauté de communes on January 1, 2002. The communauté de communes of the Annemasse agglomeration and the communauté de communes of the Voirons merged to form the present agglomeration community in 2007.
