Fischkastenbrunnen (Syrlin Fountain) at Ulm Town Hall

Fish used to be kept in the fountain on market days.

The market square in front of the town hall, bordered by cafes, restaurants, shops and galleries, is a popular meeting place for young and old, especially in summer. The square is dominated by a fountain from 1482. The oldest fountain in the city is called the Syrlin fountain. However, it is better known to the people of Ulm as the fish box fountain. This name derives from its original function: on market days it served as a basin for the fishermen's live goods. The fountain consists of a triangular fountain column and has a Gothic spire. In the colors of the Ulm city coat of arms, black above and white below, there are three knights in armor and with heraldic shields.

The fountain is very reminiscent of a church tower. It shows three knights with three symbols: the coat of arms of Ulm, the imperial eagle and the coat of arms of the imperial city.
