The Nonnensee is a lake in the urban area of Bergen auf Rügen , Vorpommern-Rügen district , Mecklenburg-Western Pomerania . It is located northwest of the city of Bergen on Rügen.


The lake was created as a meltwater lake at the end of the last ice age around 10,000 years ago.

The first attempts to drain the lake and make the area usable for agriculture go back to 1831. In that year the city of Bergen bought the lake to drain it and use it as pasture. However, the attempts were only partially successful and by 1850 the water depth had sunk to around 2.50 meters. In 1854 the city even planned a drainage tunnel to the lower Ossen . However, this plan was not implemented and instead a Dutch windmill was built in 1859 to drive a pumping station. In 1914 the mill was replaced by a more powerful steel wind turbine . In 1967 the lake was almost completely dried out with the help of an electric pumping station on the eastern shore of the lake. The continuously running water was pumped into the Duwenbeek flowing past . In the winter of 1993/94 the pumping station failed and the Nonnensee was rebuilt in a short time. It was decided to let the lake exist. The renaturation took place with the support of the Allianz Umweltstiftung . Only a few tree stumps protruding from the water still bear witness to the temporary state of siltation.

Within a few years, the lake has gained great importance for the birds bound to the water and as a resting place for migratory birds. 80 species of birds have already been observed at Nonnensee and 25 species breed here, including various grebes , mute swans , greylag goose , black-headed gull , common tern and several species of ducks . A cormorant colony with around 780 breeding pairs has emerged on the north shore of the lake . Today the lake belongs to the nature reserve Nordrügensche Bodden and Nonnensee . There is a five-kilometer hiking and cycling path around the lake. A small observation tower was built on the eastern shore of the lake for bird watching.


The name of the Nonnensee is probably derived from the fact that the Nonnensee was previously owned by the Berger nunnery.

There is also a legend according to which there was a nunnery on the site of the lake, which has sunk and where the lake was built.
