Arenenberg estate and castle

Experience world history at Lake Constance

The most beautiful castle on Lake Constance

Arenenberg Castle is situated on one of the most beautiful lookouts of the Lake Constance region. In 1816 it was chosen to be the residence in exile by Hortense de Beauharnais, stepdaughter of Napoleon I. She had the castle renovated, and furnished the rooms with style. Visitors strolling through the castle learn about the life of Hortense and her son Louis who later became Napoleon III, the last emperor of France. Today, Arenenberg Castle is an extraordinary combination of culture, hospitality and education. 

Castle with Napoleon museum

The castle belonged to various ruling families before Hortense de Beauharnais, Napoleon's mother, had it rebuilt in the style of the French empire. To this day, the castle is originally furnished. The visitors are welcomed as if they were old friends of Queen Hortense. 

With the special exhibits that are arranged every year the Napoleon museum is a new experience time and time again.

The Gardens of Arenenberg

The romantic park is perfect for a leisurely stroll. Delightful paths are leading to grottos, fountains and pavilions. The park also offers spectacular views across Lake Constance.

Restaurant / Hotel / Winery

The tradition of an open and welcoming guesthouse of old continues to be practiced today. The guests are encouraged to spend some time at the elegant hotel, which also offers modern seminar and conference rooms and a ballroom for a variety of events.

Home-grown products and regional delicacies, distinguished by the slow food movement, are available at Bistro Louis Napoléon under the heading “seasonal, regional – always fresh”.

A variety of gifts and souvenirs of Arenenberg, the gardens, the lifestyle and the history of Napoleon is available at the museum shop.
