Silbersee, Bathing lake in Langenhagen, Germany

Silbersee is an artificial bathing lake in eastern Langenhagen, south of the L 382 and north of the A 2 motorway. Its water surface covers about 6.8 hectares, mostly around 10 metres deep and up to about 15 metres at the deepest point. Three sandy beaches with adjoining lawns and large shallow-water zones line the shore, and the Paracelsus-Klinik am Silbersee stands directly northwest of the lake on the grounds of the former municipal bathing establishment.

The lake formed between 1934 and 1935 as a side effect of highway construction in the area, when excavation work left a depression that filled with groundwater. It was later developed as a bathing site and became a popular destination for families from Hannover and the surrounding region.

The lake transformed into a popular recreation spot in the 1960s, where visitors can now enjoy playgrounds, mini-golf, and dining options. These amenities shape the character of the place today and make it a gathering point for families and friends in the area.

The lake is open during the summer swimming season, and lifeguards are present on weekends and public holidays when the weather is good. Arriving early in the morning or on a weekday helps avoid the busiest periods, especially on hot days.

The lifeguard tower on the west shore once stood at the Aegidientorplatz junction in Hannover before being moved here. The DLRG watch station rescued 16 people from drowning between 2003 and 2008. The name comes from local usage linked to the nearby Hannover airport: heavy air traffic over the water is said to have made it gleam silver.
