What's that castle over there?

On the other side of the shore is located the peninsula of Duingt, home to castle of Duingt since approximately 1000 years.
The castle was formerly called ‘Châteauvieux’. This fortress of medieval origin, property of the lords of Duin, made it possible to control the route of salt trade between Moutiers in the Savoie region and Geneva. Châteauvieux has now become the property of the Certeau family.
