Klaipeda, or Memel, in Lithuania is situated at the mouth of the Curonian Lagoon where it flows into the Baltic Sea. During World War II, the city was captured by the Soviet Red Army. Unlike the rest of East Prussia, the Memel Territory was not considered part of the Soviet occupation zone, and was incorporated into the Lithuanian SSR. The city began to develop cultural activities in the 1970s and 1980s, such as the introduction of the Sea Festival cultural tradition.
