Lake Schliersee is a natural lake in Upper Bavaria in the Bavarian Alps and is named for the monastery Kloster Schliersee (“Sliersee”), established in 779 at Kirchbichl nearby Westenhofen. The lake has a surface of 2.241 square kilometres with an average depth of 20 metres. The only island is Wörth Island, located almost in the middle of the lake. In the years when the lake freezes enough, people go out for a walk on the lake to the island. During summertime, visitors go to the island for a break at the restaurant in the middle of the lake.
Schliersee is a small town and a municipality in the district of Miesbach in Bavaria, Germany. It is named after the nearby Lake Schliersee.
Among the points of interest in Schliersee, a climatic health resort is the St. Sixtus church with a Holy Trinity group by Erasmus Grasser and wall and ceiling frescoes by Johann Baptist Zimmermann. The excellent quality of the water in the Schliersee is due in large part to the construction of a system for purifying waste water from the area surrounding the lake, which was supported by the state of Bavaria with large subsidies and low-interest loans.
