Saint-Gingolph is a small town situated on the south bank of Lake Geneva. It sits at the France–Switzerland border and is administratively divided into Saint-Gingolph, Valais (Switzerland) and Saint-Gingolph, Haute-Savoie (France). Its name is derived from the eighth-century saint Gangulphus, who is said to have lived as a hermit in this region. Its division at the Morge dates from 1569: as the municipal Web site explains, it is one town consisting of a single parish with two municipal administrations and two distinct legal systems.
