Arenenberg is a small chateau at the shore of Lake Constance in Thurgau, Switzerland that is famous as the final domicile of Hortense de Beauharnais. Today it houses the Napoleonmuseum.
Arenenberg was built in the early 16th century by the mayor of Constance (1546–48) Sebastian Geissberg. The estate saw a number of owners. In 1817, Johann Baptist von Streng sold it to the exiled Hortense de Beauharnais, the daughter of ex-Empress Joséphine. As arranged by Napoleon, Hortense had to marry his brother Louis Bonaparte, and the couple were named King and Queen of the Netherlands (1806–10). The royal couple not only suffered with the demise of the rule of Napoleon, but also had an unhappy marriage leading to a separation. Hortense initiated reconstructions and renovations in an attempt to recreate the atmosphere of Malmaison. The surrounding park was possibly designed by Louis-Martin Berthault. In 1818 she moved in. Her brother, Eugène de Beauharnais, bought the nearby Schloss Sandegg and built a villa close by.
While Hortense initially spent time at her house in Augsburg, Arenenberg soon became her main domicile. At her Parisian-styled salon she entertained many luminaries. Her son Louis Napoléon, the future emperor Napoléon III, who had attended school in Augsburg, visited Arenenberg as a teenager; there he was further educated and then attended the Swiss military academy at Thun, receiving Swiss citizenship. In 1837, while he was exiled and living in New York City, Louis Napoleon received notice of his mother's deteriorating health and returned to Arenenberg. Hortense died on 5 October 1837. After mourning, Louis Napoleon had to leave Switzerland, due to French pressure, and moved to London. In 1843, in need of money to finance his aspirations, he sold the property to Heinrich Keller. Once he was emperor, his empress Eugénie bought it back in 1855. Further renovations were made between 1855 and 1874.
After Napoleon III's death, Eugénie visited Arenenberg several times before she donated it in 1906 to the Canton Thurgau. Today the château is home to the Napoleon Museum. The Napoleon Park is being restored.
References:The Château de Foix dominates the town of Foix. An important tourist site, it is known as a centre of the Cathars. Built on an older 7th-century fortification, the castle is known from 987. In 1002, it was mentioned in the will of Roger I, Count of Carcassonne, who bequeathed the fortress to his youngest child, Bernard. In effect, the family ruling over the region were installed here which allowed them to control access to the upper Ariège valley and to keep surveillance from this strategic point over the lower land, protected behind impregnable walls.
In 1034, the castle became capital of the County of Foix and played a decisive role in medieval military history. During the two following centuries, the castle was home to Counts with shining personalities who became the soul of the Occitan resistance during the crusade against the Albigensians.
