Adolf Hitler stayed in this hotel (with breaks) for two years. He wrote a part of the second part of Mein Kampf here.
A lot of political friends came over and stayed at the hotel. At ground level the family Reiter had a clothes shop. Hitler saw the daughter Mimi Reiter once playing with a dog in the Kurparks nearby. He talked with her in the park. A short affair followed. She died in 1992 (lonely and as an alcoholic) with the idea that she was the most important love Hitler ever had.
