Wasserturm
One of the most famous icons of the Jugendstil (Arte-Nouveau style) in Germany, the water tower (and small park surrounding it) is a great place to sit in the summer for a picnic or just a little rest (officially, walking or sitting on the lawn is prohibited). The park is surrounded by the Rosengarten, a conference hall of reddish brick, and the colors on a sunny day are amazing.
