Arenenberg
The Lake Constance estate where the future Napoleon III grew up in exile, kept with its Empire furnishings.
Updated 20 October 2026
Hortense de Beauharnais - Josephine's daughter, married to Napoleon's brother Louis and briefly Queen of Holland - bought Arenenberg in 1817 after the Empire fell, and raised her son Louis-Napoleon here. He spent much of his youth on this hillside above the Untersee before becoming President and then Emperor of the French as Napoleon III; after his death his widow Eugenie gave the estate to the canton of Thurgau in 1906, and it now houses the Napoleon Museum. The rooms hold Empire and Restoration furniture, much of it the family's own, in an unusually complete state. The park drops in terraces toward the lake with views to the Reichenau island in Germany. An agricultural college occupies part of the estate.
What you'll find
