Chablais museum
Château de Sonnaz
New permanent exhibition "Jump in time, 7000 years of history(s) of the Chablais". It is a real "time capsule" through 7,000 years of history. From the Neolithic era to the Annexation of 1860, the visitor jumps from one era to another and discovers the specificities of the Chablais.
In the heart of Europe, the Chablais is a territory of passage, on the road to the Alpine passes and to Italy, bathed by Lake Geneva, sometimes a link, sometimes a border. It is marked by the Roman culture, the construction of the Duchy of Savoy, the wars of religion and the affirmation of nation states.
The Chablais also lives through the eyes of artists. Works from the end of the 18th to the 21st century, evoke the infatuation of painters, engravers and writers for Lake Geneva and its environment.
More than 130 objects tell the story of this historical fresco. They illustrate the richness and diversity of the museum's collections. A nice appetizer while waiting for the future museum announced for 2025 at the Château de Rives.
