The Arenenberg in Thurgau is one of the most beautiful places on Lake Constance with its lofty location above Untersee, Arenenberg Castle and the park. The Napoleon Museum is located in the castle. Here you can see the original living quarters of Napoleon III's imperial family.

What is said in Great Britain about Windsor Castle, one can also say on Lake Constance about the Arenenberg. A castle museum with priceless international art, a park with breathtaking views, a magical spot. Everything created and shaped by international culture. Great Britain played here an important role: Queen Hortense, her son the Emperor Napoleon III. and his wife Eugénie brought many ideas from Great Britain and they created on Arenenberg a meeting place of world fame. The castle, which is still originally furnished today, welcomes museum guests like Queen Hortense’s friends.
