Château de Thonon, Medieval castle ruins in Thonon-les-Bains, France
The stone remains of Château de Thonon stand on an elevated position overlooking Lake Geneva and the surrounding Alpine mountains of Haute-Savoie.
Count Amadeus V of Savoy established the fortress in 1288 as an administrative center, which Marie de Bourgogne later renovated in the early 15th century.
The castle site serves as a central location for regional heritage exhibitions and historical education programs about the Savoyard period in France.
Visitors can access the castle ruins through a marked path from Place du Château, with information panels explaining the structure's medieval architecture.
The fortress met its end during the 17th-century conflicts between Savoy and Geneva, leaving behind substantial foundations that reveal the original layout.
