The Strandbad Wannsee is an open-air lido on the eastern shore of Großer Wannsee lake, a large bay of the Havel river in Berlin, Germany. Opened in 1907, it is one of the largest inland lidos in Europe, with a beach that is 1,275 metres (4,183 ft) long and 80 metres (260 ft) wide, replenished with sand from the Baltic coast. The entire ensemble of long, low buildings that appear to grow out of the underlying sandhills were designed by Richard Ermisch and fellow architect Martin Wagner in 1929–1930; it is today placed under monumental protection.
