From Spring to Autumn, the Hauptplatz is a sea of flowers and retains a unique character, with its old houses and monuments. Next to the traditional Plague Column, stands the Key Fountain, topped by a small bronze figure, the "Schlüsselbrunnbartele", which has become the town mascot. The square's other fountain is dedicated to Walther von der Vogelweide, the most famous German troubadour, who lived at the local duke's court.
