Silbersee in Nürnberg, Still waters in Volkspark Dutzendteich, Nuremberg, Germany

Silbersee is a horseshoe-shaped artificial lake in the northwest part of the excavation pit for the never-built Deutsches Stadion, in Nuremberg's Volkspark Dutzendteich. It was formed from 1945 when groundwater pumping stopped and the pit filled with water. The lake borders the Silberbuck, a mound made from rubble and hazardous waste.

The lake began as a massive construction pit in the 1930s, originally planned for the German Stadium. After World War II, the site served as a landfill until 1962, eventually developing into the recreational area visitors see today.

The lake lies in the Volkspark Dutzendteich, and its name refers to the silver-grey shimmer of the water. The southern section was called Pionierteich, after the pioneers who dumped rubble there until 1951. Visitors walking the shore can still smell hydrogen sulphide, like rotten eggs, at some corners.

Swimming is not permitted in this water due to harmful hydrogen sulfide concentrations that make it unsafe for contact. Visitors should stay on the walking paths and enjoy the surroundings from the shore.

The lake occupies the northwest part of the U-shaped excavation dug for the never-built Deutsches Stadion; its southeastern arm was heaped up into the Silberbuck. The landfill holds 5.53 million m³ of waste, about 0.66 million m³ of it below the waterline. In 1985 the lake bed was aerated to stop sulphate-reducing microbes from forming hydrogen sulphide; levels fell, then rose again from 1990.
