Wasserspuren, Water installation artwork in Hann. Münden, Germany

Wasserspuren is an art installation featuring water elements spread across three central squares in the old town center. The work combines interactive fountains, sound-producing features, and artistic paving with bronze and ceramic elements throughout the spaces.

The installation was created in 2000 for the EXPO 2000 world fair as a collaborative project between artists, citizens, and students. This public art initiative demonstrated a modern approach to transforming city squares into shared artistic spaces.

The project's name, Wasserspuren (water traces), is echoed by the Streuung: bronze and ceramic stones with relief surfaces set singly into the pavement at intervals of several metres, where rainwater lingers in the hollows. Some of these stones were made by citizens and schoolchildren of Hann. Münden, so residents' own work is embedded in the streets.

The installations are spread over three central squares: Kirchplatz, the area between the Rathaus and the Blasiuskirche, and the Rathaus wall. The Beeke channel in the gutter links all three, so follow it to see every element in sequence. The Klanggullys play sounds when called by telephone.

The Serie Luft on the town hall wall is a stainless-steel column topped by four sheet-metal weather vanes whose angles indicate air humidity, while blue LEDs below show the past 24 hours. Nearby, three Klanggullys — manhole covers that play sounds when called by telephone — are easy to miss underfoot.
