Arenenberg Castle
Thurgau
Arenenberg Castle is a historic estate located in Salenstein, Thurgau, Switzerland, overlooking Lake Constance. Built in the early 16th century by Sebastian Geissberg, it gained prominence as the residence of Hortense de Beauharnais, ex-Queen of Holland and stepdaughter of Napoleon Bonaparte's first wife. Hortense acquired the estate in 1817 and transformed it into a refined residence with a Parisian-style salon that attracted notable cultural figures. Her son, Louis Napoléon, the future Emperor Napoleon III, spent part of his youth at Arenenberg, receiving education and Swiss citizenship there. The castle underwent renovations in the 19th century under Hortense and later Empress Eugénie, who reacquired it and further restored the property. Today, Arenenberg houses the Napoleon Museum, preserving original furnishings and exhibits related to the Bonaparte family, and its surrounding park is being carefully restored. The castle is recognized as a Swiss heritage site of national significance, offering visitors a glimpse into European imperial history and garden culture of the 19th century.

Histoire
Arenenberg Castle was constructed in the early 1500s by Sebastian Geissberg, mayor of Constance.
Originally named Narrenberg, the estate changed ownership multiple times before being sold to Hortense de Beauharnais in 1817.
Hortense, exiled from France, renovated the castle to reflect the style of her former residence Malmaison and established a landscape park.
Her son Louis Napoléon lived and studied there before becoming Emperor Napoleon III.
After financial difficulties, the property was sold but later repurchased by Empress Eugénie, who continued renovations until 1874.
In 1906, Eugénie donated the castle to the Canton of Thurgau.
Since then, it has functioned as the Napoleon Museum and a cultural heritage site.
