Château d'Anet
In 1750, he gained the titles of "prince d'Anet" and "comte de Dreux", when his mother gave him both estates three years before she died. Little seen at the court of his cousin Louis XV of France, he preferred living at the Château d'Anet, which he continued to embellish. In order to supply water for his gardens, he created a hydraulic system which he installed in the park of the domain near the Eure River. He also enjoyed hunting on his large estate of Eu.
