The Palais de l'Île is one of Annecy's oldest monuments. As old as it is steeped in history, it was built in the 12th century.
Fortified house
The famous building isn't called the Palais de l'Île for nothing. Between the twelfth and thirteenth centuries, it was in the hands of the Lords of the Island, who held it as payment for services rendered to the Counts of Geneva.
Monetary workshop of the Counts of Geneva
Until the 14th century, the Palais de l'Île was also used as a monetary workshop. The thick stone walls were used to assemble gold and silver, thanks to the authorisation of Emperor Charles IV of the Holy Roman Empire to "coin gold and silver in his lands".
